The Tarantula's Crown

The Tarantula's Crown is a medium tier helmet dropped by the Tarantula Queen. It has an ability known as Explosion. It creates an explosion and stuns nearby players and mobs and has an overall 120s cooldown for the ability, which makes it unpopular amongst other helmets, however you can combine 2 crowns into a Mega crown, and then 2 Mega crowns into the True Tarantula's crown which has a way smaller cooldown (20 seconds).
