Overcharge

“	Can continue recovering SP after reaching the maximum. When SP reaches double the maximum, enters Charged state. Skills have additional effects when activated in Charged state (All SP will be consumed whenever the skill is activated).	”
	—In-game tip

Overcharge (Charged in-game; the Arknights Terra Wiki will use "Overcharge" outside of skill descriptions to avoid confusion with skills that can store multiple charges) is a skill mechanic in Arknights.

Overview

Skills that use the Overcharge mechanic can have additional SP once charged up to an additional 100% of the skill's SP cost (e.g. a skill that costs 30 SP need to have an additional 30 SP, for a total of 60 SP, to be Overcharged). Once the skill is Overcharged, the skill readiness indicator will change in color and it becomes more effective when activated.

Do note that regardless of whether the skill is Overcharged or not, the additional SP will be lost when the skill is activated.
