Pharaoh's Slab

The Pharaoh's Slab is a non-consumable Hardmode throwing weapon that can autofire. It is always found in the Desert Chest within the Dungeon, which must be unlocked with a Desert Key. It throws ancient stone slabs that burst into three worms upon impacting a tile or enemy. These worms home in on nearby enemies, traveling through tiles and piercing multiple times before fading after about a second.

Like most non-consumable throwing weapons, using this weapon builds up an exhaustion meter that appears below the player. Not using the weapon will make the meter slowly go back down. However, if it becomes completely filled, the user will be inflicted with the Exhaustion debuff, causing all non-consumable throwing weapons to deal massively decreased damage for some time. The meter resets after the debuff ends.
