Damn, was hoping to replace my torches with lanterns. I'll still keep some torches around to stop spawns from happening in my base, ty ty

(Consults list.) Yeah, not "base" items, but they are on the attack on sight list. The torches do count as base items, also aggro items, except for the mist light which is neither.

Hmmm...so torches do count in the "rule of three" when it comes to raids.

Dwarfs presumably have low light vision.. Must seem like 120 watters to them!

They're not in the list of "player base" objects; probably safe to assume they do not.

Why could not the dverger put more than a 20 watt bulb in them?
