Wormfeeder Rune

"Kill enemies on the Dreadnaught. Death resets your progress."

- In-game description

The Wormfeeder Rune is a consumable dropped by the Hive Ultra summoned through the use of a Wormsinger Rune. Once acquired, the rune must be charged by killing 50 enemies on the Dreadnaught without dying. After this is done, the rune will transform into a key that will open one of the locked chests in the area; which chest the key is for is chosen randomly and hinted at by the key's description.
