HellwavesMod adds simple Vortex Blocks that spawn waves of enemies when activated. Finish the waves to get some rewards, but watch out -- there might be a few surprises.

The mod also adds a few useful items to make life a bit easier. The Soul Tether can capture any unaggressive mob, and the Recaller brings you back to your spawn point—no more unnecessary walking. You’ll also be able to craft Guardians that can help during waves or fight off hostile mobs, giving you a little backup when things get tough.Guardians can be upgraded to gain various unique abilities.
