Tentacle of Cthulhu

The Tentacle of Cthulhu is a melee weapon of middling rarity. It does high damage and looks like an upside-down squid creature with bat wings.

To compensate for its high attack power, periodically (at the start of every level, and every 2 minutes after) while you own this weapon 2-15 Eldritch Spawn (depending on how late you are in the game) will appear across the map, eager to bring your flesh to serve their master.
