Overload

Overload is a potion made using the Herblore skill. A Herblore level of 96 is required to create this potion. You will receive 1000 herblore experience for making this potion. The five extreme potions and a clean torstol are the ingredients required to create this potion. This potion cannot be made with assistance. The combined cost of overload from scratch is 0 coins. Four empty vials will be left over afterwards.

When drunk, overload gives the stat effects of the extreme attack, extreme strength, extreme defence, extreme magic and extreme ranging potions combined, but only for a total of five minutes. This boost is repeated every 15 seconds during the 5 minutes, so if a player's stats are below their normal value (such as after drinking saradomin brew), then they will reach the maximum boosted values after sufficient 15 second periods. These boosts allow players to reach previously unseen level highs of 125 attack, strength, and defense. And 120 ranged and magic, all at once.

As a side effect, players will receive a total damage of 50 but divided into five equal parts (10 per second for the first 5 seconds). This damage can be healed immediately using food.

Overload also provides a 40% Magic damage boost to offensive spells (this boost stacks with the boosts from staves and void magic).

When the potion wears off, the player's stats will return to normal and players will regain 50 Hitpoints too (if not already healed).

Trivia

 * During the 5 minutes, the player's stats will temporarily drop by 1 in the usual way after each minute, but then will jump back to their extreme values again at the next 15 second boost repeat.
 * When first released, the Overload could be used in PvP situations, but within 48 hours, this was changed so they cannot be used in any PvP situation, dangerous or safe.
 * According to Jagex, it "racks the body with spasms and burns the digestive tract'. However, players are still allowed to eat food, even if overload does "burn the digestive tract."
