Betsy's Wrath

The damage is not the point. Every volley plants a curse that strips a large slice of armor off whatever it touches, which multiplies whatever your real weapon is already doing. Fire once, swap back, keep it refreshed. In multiplayer it is one of the strongest things a single player can do for everyone else in the arena.

The three fireballs arc and fall, and they burst on terrain as well as on enemies, so a shot into the floor beside a target still spreads the effect over a wide patch. Against anything with a big hitbox all three usually connect, which makes the timing forgiving even while you are dodging.

Treat it as the direct upgrade to the Golden Shower. Ichor layers on top rather than overwriting, so running both cuts deeper than either alone. Betsy has no immunity to her own curse, so it works in the fight that drops it. Against other players it does nothing at all, which rules it out for PvP support.

Every Old One's Army weapon is lifted from Dungeon Defenders 2, the game the whole event crosses over with, and this one keeps its original name.
