Summoning Ring

The  is a  Dungeon Item that can be used to absorb the souls of Mobs you kill. You can then summon these mobs using, the cost depending on the power of the mobs.

This item uses the Necromancy mechanic and it does not need to be held for souls (purple skulls) to drop on the ground so you can pick it up. It just needs to be in your inventory. Due to this, it is often used in combination with other necromancy items so the player can use their main sword for the larger damage output instead of the Reaper Scythe or Necromancer Sword.

This is also very useful for enderman slayers as you can pick up a lot of souls of tank zombies from The Catacombs and use them to block the Voidgloom Seraph so you can damage it while it can not damage you. This also makes moving to the beacons that the Voidgloom puts down easier to move to and you can see where the Voidgloom places it better.

Obtaining
The Summoning Ring can be dropped from a Floor VI Post-Boss Chest. It costs to open from the Obsidian Chest and Bedrock Chest.
