Toggle

From ParagonWiki

A toggle is a type of power that is either continuously active or not active in any way (like a light switch), compared to auto powers which are always active and "click" powers that activate immediately. While a toggle is on, the user receives some kind of persistant benefit (such as stealth or increased defense) as long as the toggle remains on. This benefit (with rare exceptions) comes at the cost of a slow yet nearly continuous drain to Endurance, with other possible effects such as decreased movement speed. When toggles are deactivated (either deliberately by the player or by a method of shut off below) toggle powers recharge just like other powers.

Toggles deactivate automatically if the user does not have enough endurance to sustain the effect, is affected by a number of status effects (stunned, slept, held), is defeated, or is hit with a Toggle Dropping power during PvP.
