My first purge occurred today. I build walls around my base but are pretty useless. Mobs of the purge arrived but when facing the walls they teleported inside my base and on top of walls.
Why should I build walls in pve if mobs can get rid of it?
Often the mobs spawn in and just stand there. If I give them a nudge with an arrow they start walking. That’s when they are most likely to teleport - always to the exact same spot on my wall.
