1. Skepticism: when transforming a creature into an object, you don't get XP. When transforming it into another creature, you get the XP for defeating that creature (if you kill it, of course), not what it formerly was. 2. Close Encounter - won't open Chests of Evil. (!) 3. Xenochemistry - transformed potions won't stack.
1: Intended, really. If you transform it into an object you take a chance, just like you miss the exp on animals if you're a vegan. 3: Thought I read about this, I'll try to find that info back. 2 looks like a bug though. I'll file it.
Actually, the stacking bug is a bit odd - you can't manually stack the potions, but the Sort button will do it.
In addition to the above, if Skepticism is used to transform a monster in a Monster Zoo into an item it makes it impossible to complete as it doesn't mark the monster as killed.
Scratch what I said about the stacking problem and sort - that often doesn't work, either. So far I've seen no discernible pattern, unless it's potion type/name . . . . .(that is, specific potions just won't stack, some will).
Sometimes , minions will totally ignore the fact that you revealed some monster to be a piece of equipment , and will fight it anyway. Said piece of equipment will then proceed to kick their ass : That's one mean leather cuirass.
