You get Wavedancer post Thespian, but the weapon requires 3 minion slots to use. At that point in progression, there is NO WAY to get 3 minion slots without playing with other mods. Obsidian armor only gives 1 slot from the chestpiece and the only other pre-queen bee item that gives a minion slot is the flinx fur coat, which also takes the chestplate slot. The Slot requirement should be reduced to 2 or this weapon should be rebalanced and moved post-queen bee.
