The node I am using is in a village inside one of the larger houses... so now I have a house that is packed with wisps. There has to be at least 20 in there. Anyone got a good way to kill these without burning down the house (so no lava)? Do they take damage from a tesla coil? I think they are immune to the lightning wand but not sure about the tesla coil. My other thought is maybe putting a few iron golems in the house. The wisps would have a hard time staying out of melee range.
