Corruption sigil

The Corruption Sigil is an item obtained from the Barrows minigame loot chest. At least one Barrows brother needs to be killed to be able to get the sigil, and killing more brothers will increase the drop chance. The sigil is only dropped when a dragon defender is equipped or in the player's inventory.

The sigil can be combined with Dharok’s greataxe, Verac’s flail, Guthan's spear or Torag's hammer to get a corrupted defender.

The sigil was announced as a "corrupted sigil", but the item name in game is corruption sigil.
