I was fighting an Unfriendly AI on floor 1. I used Dump Toxic Assets and now the Unfriendly AI has Bad Credit. What is odd about this is now he is regenerating health at a rate of once per turn. I've never seen an Unfriendly AI regenerate health before so my only thought is that Bad Credit is causing this. Attaching my save file. He is near the Unfriendly AI. If you deal damage to him, you can see that he is regenerating health every step. (Don't use Acid Projector, you'll just kill him.)
I'm not convinced this is a bad credit problem - I've seen this kind of monster regen quite a few times. Unfriendly AIs stand out for it, but I've also seen it in Deths and even diggles, with no skill/spell used on them, just ordinary melee damage. That said, are you running a hot fix build? (Not sure which one they're up to now...)
I am running the fifth version of the hotfix. I don't see anything in the files that would give them health regeneration. <monster level="2" name="Unfriendly AI" displayName="Unfriendly AI"> <stats xpValue="32" numFig="6"/> <palette tint="90"/> <secondarybuff amount="4" id="10"/> <!-- armour --> <secondarybuff amount="6" id="7"/> <!-- block --> <resistances piercing="10" voltaic="-3" toxic="10" putrefying="10" asphyxiative="10"/> <damage piercing="3" voltaic="3" slashing="1"/> <info text="This shows the tangible threat of the Unfriendly AI problem." latin="(roboticus vulgaris)"/> </monster>
