>>49272544For beginners, make a temporary base across the map on day 29 and chill there for a day or two, Deerclops always spawns on the player from the ocean, so you can spawn him across the map and then just fuck off back to your actual home base. He'll despawn after a while.
Spawning him in the swamp or in the desert will let the natural mobs of the area attack him, tenticles, merms, werehounds etc. I've used the dragonfly and the bearger to kill it before but that requires a bit of kiting and finesse.
