Hungering Blossom

The Hungering Blossom is a craftable Hardmode accessory that restores 50% of the player's maximum mana after losing 80% of it, but additionally gains 10 stacks of "volatile energy", indicated by a gauge below the player. For each stack of volatile energy possessed by the player, their attack speed increases by .20%. However, they begin to take damage over time, with the intensity based on the amount of possessed volatile energy stacks; each 10 stacks increases the damage per second by 1. If the player reaches 100 stacks of volatile energy, they will be instantly killed. Volatile energy naturally decays over time, with each stack decaying once a second.
