Ragnarok patch history: Alpha to the end of Thai pre-Renewal

Research edition, 2026-10-28. This is a sourced patch-note reconstruction, not a claim that every maintenance patch or numerical balance table has survived.

For synchronized developer and player guides, start with the Thai RO Timeline Bible.

Scope: English/international Alpha and Beta are preludes. The Thai service begins with September 2002 CBT. No separate Thai Alpha deployment has been established. Thai-language coverage of an English server is labelled accordingly.

Endpoint: stop immediately before the announced Thai Renewal maintenance on 9 November 2010. The original operator notice calls that new client EP13.2.1. The precise final pre-Renewal maintenance contents still need recovery. thai_renewal_original, thai_renewal_day

Reading dates: “By” means already present by that document date. A schedule does not establish successful deployment. Test-server dates stay separate. Undated entries follow development lineage; their positions do not prove Thai order. A Wayback capture date is distinct from the original document date.

Reading Episodes: numbers follow Thai evidence where recovered. “Era” means context, not a separate numbered release. Early mirror labels and retrospective book contents are provisional; Ayothaya’s precise Thai subnumber remains ambiguous. Alpha/Beta preludes have no assigned Thai episode. Episode labels do not certify the mechanics or complete contents of a build.

2. Beta 1: skills and Mage era

Region: English/international prelude. Date: 2001-12 (reported period). Date status: unresolved.

Episode: Alpha / Beta; number unassigned (not_assigned). International prelude. No authenticated numbered Thai episode applies to this build. global_beta_changelog

• Community chronology describes skills, job progression and Mage becoming available; its December 2001 period is an international reference. (unverified_compilation). global_beta_changelog
• A 2002 Mage guide supplies a flat SP Recovery skill candidate; natural recovery is a separate unresolved rule. (contemporary_cross_region_candidate). mage2002
• March 1, 2002 Japanese discussion reposts an approximate natural-SP interval of 7.54 − 0.06 × INT seconds per 1 SP; its table doubles sitting recovery. This is a cross-region candidate, not a Thai formula. (contemporary_reposted_formula_candidate). jp_sp_discussion_20020301

Still to recover or qualify: exact_beta1_build, job_change_level, natural_recovery, exp_curve, drop_rates.

3. Beta 2: Thai-language support for English server

Region: English/international prelude. Date: By 2002-07-17. Date status: unresolved.

Episode: Alpha / Beta; number unassigned (not_assigned). International prelude. No authenticated numbered Thai episode applies to this build. english_beta_thai_index

• Original July 17 guide lists Knight, Hunter, Assassin, Blacksmith, Priest and Wizard job locations; identification uses a consumable costing 40 zeny. (original_operator_document). english_beta_identify
• Preserved attributed notice says Swordman recovery gains MaxHP scaling; the skill boosts healing-item recovery by 10% per skill level, while VIT adds 1% per point. (attributed_notice_unverified_region). beehive_beta2
• Same notice reports 5% death EXP loss and 3% dungeon item-loss chance, AGI-to-DEX cast-time scaling change, and revised monster stats/prices. Penalty denominator and Thai applicability unresolved. (attributed_notice_unverified_region). beehive_beta2
• FAQ section6 says planned initial Thai version was Beta2; beta would be free. Original mid-August schedule could change. It is prelaunch intent, not the actual September launch date or exact deployed formula. (verified_announcement_not_runtime). english_beta_faq_20020722
• Operator reports all areas restored, including Training Ground and new maps, as of07:20 Thai time. This English-service report is distinct from the unrecovered September18 Thai Training Ground notice. (verified_status_notice). english_beta_training_fixes_20020717
• Announces rollback toJuly16 state because a clothing item (Thai name เสื้อขนมิ้งค์) was overpriced onJuly17. No exact price or item ID supplied; completion remains unverified. (verified_schedule_not_completion). english_beta_rollback_20020718
• The July 11 announcement makes the English Beta 2 client available and schedules English service for July 16, 2002 at 08:00 Thailand time. A separate July 17 notice reports Chaos and Loki operating normally as of 07:20. These establish a planned opening and a later operational observation, not proof of an on-time July 16 launch. (original_schedule_and_later_service_report). english_beta2_download_schedule_20020711, english_beta2_service_status_20020717
• A July 17 notice warns that missing client patches can cause character-stat, second-job and saving problems. It establishes a compatibility requirement without a numbered patch manifest or HP/SP formula. The July 11 N Protect notice concerns Korean deployment; English and Japanese servers were explicitly unchanged at that time. (original_operator_client_and_region_qualification). english_beta2_patch_requirement_20020717, korean_nprotect_notice_20020711

Region: English/international prelude. Date: 2002-07-22 (reported change). Date status: original_operator_note.

5. Thai closed beta

Region: Thai. Date: 2002-09-16 (schedule + launch-day report). Date status: original_schedule_plus_launch_day_report.

Episode: 1.0 (provisional) (mirror_label). Early Thai numbering follows the preserved notice mirror; original launch records establish dates, not this episode label. thai_mirror

• Thai CBT starts September 16 at 18:00 on Chaos, Loki and Iris. Original launch-day report says service has operated over five hours. (original_operator_documents). thai_launch_original, thai_launch_day

• Hardware and network installed and under test; planned servers increased from2 to3: CHAOS, LOKI, IRIS. Software problems still being resolved withGravity. Launch schedule promised the following week. Official Thai website opened. No launch date announced here. (verified_prelaunch_notice). thai_progress_20020831
• Thai Operation Team confirms client downloads and capacity problems from heavy demand, continued availability and alternative mirrors. Establishes distribution chronology, not build or formula. (verified_distribution_notice). thai_client_download_20020914
• Undated original Thai Swordman/Mage guides captured in December 2003 print passive HP recovery of 5 × skill level and SP recovery of 3 × skill level per 10 seconds while sitting or standing idle. These are skill tables, not natural-regeneration formulas; complete runtime terms and beta applicability remain unverified. (original_guide_later_capture_not_beta_runtime_proof). thai_swordman_guide_2003, thai_mage_guide_2003
• The first announcement, indexed July 3 but undated in its body, reports the June 13, 2002 Gravity/Asiasoft agreement and proposes a mid-August Thai Beta 2 opening. An August 12 plan moves the tentative opening to early September, with installation August 19–25 and internal tests August 26–31. These were plans, superseded by the September 16 launch; they are not a separate Thai Alpha service. (original_prelaunch_plans_not_completed_dates). thai_initial_announcement_july2002, thai_progress_20020812
• A September 11 notice schedules client downloads from September 14 at noon and partner-ISP registration from September 16; an alternative boxed client/manual/ID package costs 149 baht. A September 20 notice confirms CBT had operated since September 16 at 18:00 and announces extra limited client-CD/ID distribution from September 21. (original_distribution_schedule_and_launch_confirmation). thai_cbt_participation_20020911, thai_cbt_extra_ids_20020920
• The participation notice says the client program can continue into OBT, while the August plan discusses IDs continuing into paid service. Neither statement establishes CBT character retention or overturns the separately announced CBT wipe. The first announcement explicitly disallows transferring foreign-server IDs to Thailand. (original_operator_distinct_continuity_scopes). thai_cbt_participation_20020911, thai_progress_20020812, thai_initial_announcement_july2002
• Another undated Thai operator guide, captured in December 2003, says weight over 50% stops ongoing HP/SP increase, while items or skills can restore it; over 90% prevents attacks and skills. It supplies no natural recovery amount or interval. Exact equality boundaries, passive-skill exceptions and beta applicability remain unresolved. (undated_operator_guide_not_beta_runtime_proof). thai_interface_guide_2003
• Other operator guides describe ambiguous HP after death, unspecified 1% Base/Job loss, 50 zeny for training enrollment and Base-only progress from Fabre in the second training area. These are undated guide descriptions, not confirmed beta rules: the revival routes are not separated, and training Fabre must not replace ordinary field Fabre rewards. (undated_operator_guide_not_beta_runtime_proof). thai_basic_guide_2003, thai_training_guide_2003, thai_training_course_guide_2003

7. Lutie seasonal addition

Region: Thai. Date: 2002-12-13 (reported/scheduled). Date status: reported_in_mirror.

Region: Thai. Date: 2005-09-07 (reported/scheduled). Date status: original_client_patch_requirement.

Episode: 9.0 era; client policy update (contextual_assignment). Dated client change between High-Class and the announced Einbroch update; no separate official episode number recovered. thai_multiclient_original_20050906

• Official client gains supported multiple windows after the September 7 patch. The September 6 notice tells players to launch Ragnarok again normally; available window count depends on machine resources. (original_operator_client_notice). thai_multiclient_original_20050906
• A cumulative High Class client page, indexed September 9 but captured November 24, later says Multiple Login was added on “7/11/2548”. That later-edited page does not overturn the separate September 7 Multiple Client notice. Whether it describes the same change, a revision or a date error remains unresolved.

24. Novice Guild War on main servers

Region: Thai main-server trial. Date: 2005-09-26 (reported/scheduled). Date status: original_operator_same_day_deployment_report.

Episode: 9.0 era; unnumbered activity update (era_context_not_numbered_episode). This is a separately dated Novice Guild War update between High Class and Einbroch. The original notice does not assign an Episode number. thai_novice_guild_war_original_20050926

• The operator reports Novice Guild War added to main servers on September 26, 2005 after Sakray testing. Initial announced hours are Tuesday and Friday, 18:00–20:00. It is still described as a main-server trial; rewards will be announced later. (original_operator_deployment_report). thai_novice_guild_war_original_20050926
• The captured rules allow Novice, High Novice and Baby Novice at Base Level 20 or below. Guild masters are excluded to prevent Urgent Call bringing other classes inside. That exclusion has no separate start date on this later captured page. (original_operator_rules_with_later_amendment). thai_novice_guild_war_original_20050926
• Four castles cannot hire Guardians. During war, Novice Guild War Agents in Prontera, Geffen, Payon and Aldebaran send players to Izlude; the entrance is beside the Arena entrance. Map details, castle-object HP and respawn rules remain unverified. (original_operator_rules_with_later_amendment). thai_novice_guild_war_original_20050926

• A later notice schedules a change from October 25, 2005: main-server Novice Guild War on Tuesday/Friday 19:00–21:00; Sakray on Wednesday/Saturday 19:00–21:00. Its September 13 body header conflicts with an October 13 index date. The announced start is explicit, but completion is not established.

Test-server schedule: 2005-10-03.

Separate availability bound: by 2005-12-08. thai_gravity_interview_20051208

• Original September 28 notice schedules Thai Sakray October 3 and main servers October 17, 2005. The manual patch notice independently repeats October 17 for main servers. Keep the December 8 already-live bound; successful October 17 deployment still needs corroboration. (original_operator_schedule_recovered). thai_einbroch_schedule_original_20050928, thai_einbroch_manual_original
• Announcement lists 183 new cards, Einbroch and Einbech, new monsters and RSX-0806, first-job quests, The Sign/Geffenia, mining dungeon/fields, Blacksmith and Alchemist Fame with top-10 product benefits, Turbo Track, and new items. Numerical card/drop/skill tables are not supplied. (original_announced_feature_bundle). thai_einbroch_schedule_original_20050928
• The announcement promises no rollback, character reset or loss/change of existing item properties on main and Sakray. Existing client can auto-patch. Manual notice says roughly 12 MB split across four files, staged from September 29, and requires the High-Class installation.

• Council reports changed Teleport interaction and Guild Dungeon restrictions; new-job reskill requested rather than announced as available. Future roadmap is a proposal. (operator_council_current_state). thai_rolc_2006
• An August 8 guide explicitly places the gradual 10.3 update on Thai Sakray. This conflicts with treating the promotional August 8 date as a confirmed main-server launch.

30. Rachel and socket enchanting

Region: Thai. Date: Unresolved. Date status: unresolved.

Episode: 11.1 / Evolution Begins (contemporary_thai_editorial_label). Thai-focused contemporary reporting names the preceding episode. Its displayed October date conflicts with a future-September preview, so it cannot establish a precise launch date. thai_veins_preview_20071019_conflict

• Rachel, Holy Ground and slot-enchant systems are content candidates; exact Thai date and per-item eligibility still need original notices. (cross_region_reference). iro_updates
• June 2007 Thai-language guides describe the collective Holy Ground opening and later character access quests. They also supply monster/drop leads, but do not identify a Thai production launch day; image-based monster tables remain unrecovered.

• Recovered operator quest guide 373 lists Hammer[2] ×1, Rough Wind ×5 and Empty Scroll ×1. Helping Maheo awards four Freezing Snow Powder; returning the necklace to Urstialla then awards 700,000 EXP; the guide does not label this as Base or Job EXP. Its airplane.gat website header is explicitly a substitute map label, not the in-game starting location. The June 28, 2007 archive capture is not a publication or rollout date. (original_operator_quest_guide_recovered). thai_ice_necklace_quest373_original
• Operator guide 380 requires the preceding wizard quest and four Freezing Snow Powder to extinguish the four fires on ice_dun03. It states the fires return two hours after Ktullanux is killed and lists Water level 4, Brute and HP 4,417,000.

Episode: 13.1 (contemporary_thai_label). Number identified in contemporary Thai evidence; date and completeness remain separately qualified. thai_brynhild_test

• Thai item-testing article says 13.1 has arrived and a Thai guild already created a new Godly item. This establishes availability by May 23, not launch on that date. (contemporary_firsthand_observation). thai_brynhild_test
• New World expedition is content context; the iRO June 9 date cannot be used for Thailand, which the Thai report already places earlier. (regional_date_constraint). iro_ash, thai_brynhild_test
• The archived March 15 operator index lists an Ep.13.1 ASH VACUUM announcement dated March 3, 2009. Its now-recovered body, captured March 16, still ends with “coming soon” and gives no exact test or main-server date.

Gaps that prevent an authentic automatic patcher

• Thai CBT numerical natural HP/SP recovery and the exact date it changed.
• September/October 2002 level tables, death-penalty basis, party rules and production rates.
• Complete old/new monster stats, drops, skills, spawn locations and respawn delays.
• Original notices for mirror-only dates; successful-deployment records for schedules.
• Exact Thai rollout dates for Einbroch, 10.4.1, Rachel, Nameless, 13.1 and 13.2.
• Weekly 2009–2010 patches between The Unknown and Renewal; separate server/event/shop overlays.
• Matching old map/client revisions and a deliberate continuous-character migration policy.

Why the early mechanics are still candidates

The preserved BEEhive Beta 2 text describes HP skill/item scaling and death penalties, but its effective date and regional scope are unresolved. Original July 2002 Asiasoft pages explicitly support the English server. Neither source establishes the later Thai CBT natural regeneration algorithm. The July 2003 Athena code remains an independent emulator candidate, not an official Thai reference.
