ItemName.BoringBow

This one is not playable in any sense. It has no name string, no stats and no projectile, so if you force it into an inventory it shows up as a raw internal identifier and does nothing when swung.

It is left over from the Dungeon Defenders 2 crossover. Three bows were drafted to represent the same class, and this was the one cut when the other classes ended up with two weapons each. The two that survived are the ones you can actually use. The odd part is that it persists at all: most unfinished items get stripped when a world loads, but this one stays put once it is in your inventory.
