Polarities Mod/Maw of Flesh

The Maw of Flesh is a Hardmode accessory that is dropped by the Wall of Flesh when defeated without taking any damage from it. When equipped, it grants the player a dash similar to the Shield of Cthulhu that deals no damage by itself, but also summons a fleshy wall with infinite vertical reach that travels forwards. Damaging any enemies in its path, it speeds up over time, having an incredibly long range that makes it useful against crowds of enemies.
