Here’s a neat idea, add a “ritual” area in the warzone that a player can pay a specific price to change a placed spawner into one of their choosing.
This being limited to ones that aren’t super op or would break anything ofc*
Say spending 5mil to change the spawner to wither skelly for 10 minutes
Also maybe add strong mobs in different areas of the warzone.
Wither Boss in the volcano, Elder Guardian at the water tower, evokers/vindicators/ravagers (1 of not all) in one of the town areas.
this would be fun to fight and maybe get a little loot out of it.
though this idea would be trumped by actual custom bosses which would be way cooler.
