Overload

Overload is a reward that can be purchased from the minigame Nightmare Zone using reward points. These points can only be received by playing the minigame. Overloads can not be used outside the minigame, due to many players describing overloads as trivialising bosses such as God Wars Dungeon bosses. One dose of Overload costs 1,500 reward points.

Using an overload potion raises all of the player's combat levels (excluding Prayer and Hitpoints) by 5-19 (5 + 15% of level, rounded down), and damages for 50 hitpoints. The absorption potion will not absorb overload damage.

This boost is repeated every 15 seconds for 5 minutes. It is a popular misconception that overloads will fully restore a player's stats every 15 seconds. This is untrue, as overloads simply reapply every 15 seconds. This property is useful to players who are using Saradomin brews to restore lifepoints, as the overload's frequent boosts help to counter the Saradomin brews' stat drain. After the five minutes is up, the overload's stat boosts will wear off entirely, and the player is healed 50 hitpoints. You will need to re-dose every 5 minutes while in a dream, to effectively use this potion in Nightmare Zone.
