Two questions. I never use NPCs except for this playthrough. Can you tell what levels of which class an NPC has? I have Furnok and I forget if I gave him 1 or 2 levels of fighter. Also, how do you use holywater? I have a ton of it and I cant seem to use it in battle. I find nothing on the radial menu. Thanks!
You can do some reverse math on his BAB, or check his feats, as a level 2 fighter, you should have added 3 feats to him. I never used Holy Water, but I have thrown plenty of flaming oil and even the acid the Traders sell. Should work the same.
Yes, you have to equip it as a weapon and throw it at the bad guys. It's actually pretty deadly against low level undead, also your cleric can create it at level one, (Bless Water).
Does it have any kind of splash effects or is it single target only? Sounds like it would be quite handy at the start of the game when you're cleric's turning ability isn't so hot to be able to nuke all the undead yet.
