An Overload is a potion that can be purchased from the Nightmare Zone minigame for 1,500 reward points per dose. These points can only be received by playing the minigame and overloads cannot be used outside the minigame. Drinking 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 causes 50 hitpoints of damage in chunks of 10. Absorption potions will not absorb damage incurred via drinking an overload, similarily to eating a dwarven rock cake.

Furthermore, it is not possible to drink an Overload potion while below 50 HP. However, if a player drinks an overload potion and immediately lowers themselves to 50 HP or below before the first hit of damage is applied then the player will die from the overload hits if they do not heal. When the overload runs out, the 50 HP that was lost is then restored.

A player drinking a dose of overload.

The boost is reapplied 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 hitpoints, 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 and the players level set back to their actual level rather than progressively decaying like most boosts do, while also restoring 50HP as mentioned previously. You will need to re-dose every 5 minutes while in a dream to effectively use this potion in Nightmare Zone.

## Stat boosts by level

Boosts to most combat skills is calculated with: ${\displaystyle \lfloor SkillLevel\times {\frac {15}{100}}\rfloor +5}$

Level Boost Level Boost Level Boost
1-6 +5 34-39 +10 67-73 +15
7-13 +6 40-46 +11 74-79 +16
14-19 +7 47-53 +12 80-86 +17
20-26 +8 54-59 +13 87-93 +18
27-33 +9 60-66 +14 94-99 +19
