And should I drink these potions to get rid of 'em?
Mutagenic Glow is contamination, right? Two hits of Irradiate (from Radroach) can give you severe contamination. Or some of that contamination could have been self-inflicted.
I wondered about the radroach, but the description for Irradiate doesn’t say anything about mutations. Aside from drinking a mut pot, how would one self-mutate?
contamination can cause mutation though.
If you cast high fail-rate spells repeatedly, it can happen. Used to be a common worry for transmuters and invisibility specialists. (Because invisibility would also gradually contaminate you.)
You can still force it with high fail-rate spells, with radroaches, and with mutagenic fog.
If you want mutations you can also follow Xom.
Unequipping something with ^Contam is also enough to give you severe contamination.
If you’re seeking mutations, contamination is probably not a good choice, since it’s skewed towards giving you bad mutations.
