Generally the idea would be arrows wall trap but you could put them in the center , choosing the direction(and/or) rotation similar to firebars.
#Trap Totem
silver lake
dreamy stag
confirmed
"pillar turret" in the confirmed list, under Traps
though idk if it'll have rotation, I like that idea
cosmic plaza
cent?
pallid aspen
I assume LagiaLugia meant 'center' as in you could place these objects in the middle of a room
pallid aspen
though idk if it'll have rotation, I like that idea
layer 50 on the same block to make a bullet hell room
silver lake
