The bots don't use the "default class" spell lists for npc's if that's what you mean by default. I know what you mean about it being tedious since I made the bot spell lists. The default npc lists are 1 through 12 in the npc_spells table but the bots are 701 though 712 in that table. If I missunderstood what you meant by default then nm. Anyway, it would probably be easier to start with what I have and edit/modify rather than start from scratch. Yes the cleric only has 2 spells for healing, but that's just because I modified the ai to use one HoT and one Real Heal... CH being the best choice. Certainly an ai written to handle more heals would be better.
Here's a link to my sql.
