the best golem seems to be the support mage. it can heal the team if you stay near it, has a stun rune which is very valuable in enclosed spaces (raids) and if you give it hels staff which is a very cheap weapon you also get a dmg buff, even better if it's the ymir combat staff and you're all using ymir weapons. if this can be combined with the sentry statue then the room you put it in will be the most guarded with constant stuns
Is the manor really worth it? There was only a couple things I cared for but you can build them all in one house. The fishing nets, fire runes, and the oats. Most of it didn’t need to be cleared.
