The Dominion crossbow is a reward from Dominion Tower. It requires level 90 Ranged to wield, but may be obtained without the ranged requirement. The crossbow is a one-handed weapon, unlike the staff and sword counterparts, but it does not currently have an off-hand counterpart. It is received as a random reward through the rewards chest determined by how high a player's dominion factor is. It can only be used in the arena but can be equipped anywhere inside the tower. Upon leaving the tower, the Dominion crossbow will be unequipped to your inventory or stored in your bank if your inventory is full. If both are full, it will be dropped. It degrades similar to chaotic weapons but only lasts for 100 shots before crumbling to pieces. It is also possible to receive more than one from the Rewards Chest.
This power-up is unlocked after the player has reached floor 25 in Endurance mode.
