Allows you to create a sacrificial altar to summon a mob
VtAlters-thumnail.png
VtAlters is a powerful tool suitable for creating a place where players can summon bosses on their own.
With VtAlters, you can create an altar, and players simply need to place the correct items you’ve predefined onto the pedestals and use the summoning item to activate the ritual. The boss will be summoned in a straightforward manner, with simple commands and functions that make it easy for you to get started and create your own custom altar.
