Should be fixed in next release, I think. Need to test. I believe they were missing a proper hostile faction in quest.txt, so they inherited the neutral one from their creature entries.
Spell is "enemy_schamane_blitzzone", and the damage is pure Magic DOT. Interestingly, the goblin riders were the only creatures the devs gave this spell to, so it's essentially a restored spell as well.
It happens from time to time.
It worked decently, not great. Enemies would like to switch to their melee weapons even just to cast their ranged CA's, and often didn't switch back. Their switching A.I. sucks IMO, you don't get nearly enough of their proper ranged attacking. But I can revert them back to switching for PFP.
All I did was add a missing spell and enable his turrets. I tested him too before release. I'll review all his animations - the usual culprit for lacking special move behavior.
Kraal didn't do anything but bite in vanilla. I think literally every single special move was broken, including the turrets.
Generally true, also remember that one of his special moves is a hard-hit bite, and enemies will often doggedly persist trying to execute a given special move. If you're constantly kiting he may be trying to do his hard hit but unable since you keep moving. Just a thought. Bugged animations may also be a possibility.
He won't, in PFP, since you don't actually kill him. He's killed via script. Being able to strike the killing blow is only in EE and other mods.
Could be something introduced by the doublesided flag in his surface entry, but normally that flag has the opposite effect. He's also got SURFACE_FLAG_ZMASKED in one of his entries, might be doing something to his hair. Will investigate.
I should be able to cook something up. Least likely are the enemy taunts and the Gahanka lines, at least without coding changes, but we'll see.
