Overcharge

Overcharge, sometimes called Overheat, is a mechanic used by Sienna and Bardin.

Generating Heat
Heat is generated by using Bright Wizard staves and Dwarf drakefire weapons. Usually the primary attack would generate a small amount of heat, while the the charged attack will generate considerably more heat. Also, each weapon generates a different amount of heat.

Venting
The player can vent their weapon by pressing the reload button(R by default). By venting, the weapon will lose heat but doing so will also deal damage to the character. The weapon will passively vent over time.

Overcharge Bar
Each time the player generates heat, the overcharge bar will fill. The bar has 3 sections. Venting while in the first section won't damage the character, the other 2 sections will. If the whole bar is filled the character will get downed.
