I'm dying to know. I didn't exploit the ability because I thought it must be a bug but my prays and bug board posts went unanswered.

Therefore ingesting magical stuff is ok. You do gnaw on bones after all.

But I wanted imm confirmation. For example, you're immune to poison but you can give yourself alcohol poisoning - seems off.

I'll have to look at the code, but I thought Wights were prevented from eating anything that wasn't made of bone. I suppose a bone-material pill still has some potential there in that case.

The question is: Do pills and potions work because they are rapidly metabolized by PCs or because their ingestion is itself a magical process? I'm inclined to say the former, in which case they probably shouldn't work for Wights.

Now I'm curious what the code does!

Which has odd affects if you eat seaweed. There are a host of other wight-related bugs that I posted to the bugboard including:

Ability to catch plague - this reduces strength and makes you contagious without causing damage or stopping regen.

Then there are area related progs which can blind you or make you fall asleep. Also the fungus in the mines does things to you and the echos make me think that should be related to biological processes. But if druid spores are a thing that undead have to deal with it would be consistent that abandoned mines spores would be too.

I'd guess the code probably just prevents you from eating food.
