TLDR. fa734cc8a ported the KMS2 npc skill lists into 2,004 npc files so the server AI scripts, which number skill slots the way KMS2 npcdata does, find the slots they call. It missed 11 mobs. Their AIs call slots 2-6 that don't exist in our files, so they stand idle: Captain Moc's Plundering Skelic Vikings never spin and his Gunnery Crewmen never fire. This ports the same lists for those 11, in every environment of each file.

Changes

NPC	Name	AI calls up to	Skill list
21400228, 21402228	Plundering Skelic Viking	slot 3	50100052 lv 1, 2, 3
21401228, 21403228	Plundering Skelic Viking	slot 5	50100052 lv 1, 11, 12, 13, 14
21401229, 21402229, 21404229, 21405229	Plundering Skelic Gunnery Crewman	slot 2	50100054 lv 1, 2
21406229, 21407229	Plundering Skelic Gunnery Crewman	slot 3	50100054 lv 1, 3; 50100079 lv 1
22000011	Revenant Zombie	slot 6	50100010 lv 1, 2; 50100011-50100014 lv 1

Why these are safe

• Source: the KMS2 debug client's server npc data (npcdata/214.xml, 220.xml). The server AI folder is byte-identical to that client's AI folder for all 1,642 shared scripts.
• Each new list keeps the existing slot 1 unchanged and only adds slots after it, and every added skill and level exists in this repo's skill/ data.
• Across every npc in both datasets, no list is a shifted copy of the other. 40 npcs have the same skill at a different level in an overlapping slot, and 3 (Urpanda 22000024, Urpanda's Ghost 30000012, Revenant Zombie's Ghost 30000002) have different skills; all of those are left alone.
• Probabilities are split evenly, remainder on the last slot, as fa734cc8a did (e.g. 21000105's 12,…,12,16). None of these 11 AIs reads them.

Test plan

Re-ingest, then in Captain Moc's chaos raid (field 02000327): the Plundering Skelic Vikings chase and spin-attack, and the Gunnery Crewmen fire, including the upper ones from the start of the fight. Before this they stand facing the player, and the server logs AI script ... references skill idx [...] but ... has only 1 skill slot(s) for them.

Verification

Tested in game on 2026-11-02 with the same slots applied server-side: the Vikings spin and attack, and the gunners fire.

Summary by CodeRabbit

• Gameplay
  • Updated several NPCs’ skill configurations across supported environments, expanding the range of skill levels and combinations they may use.
  • Adjusted skill-use probabilities so these NPCs can use multiple configured skills rather than relying on a single skill entry.
  • Added multiple skill options to one additional NPC, while retaining its existing cooldown setting.

Align the CN skill slots and large-vomit calls.

Swapping only indexes 3 and 4 would make the phase-2 and phase-3 large-vomit calls use the nail skill. Update those AI calls and also swap the small- and large-vomit slots.
