Overload (-)

An overload (-) is a potion that boosts all the player's combat stats by 4 + 10%, while damaging them for 50 hitpoints. This boost is repeated every 15 seconds until the effects wear off, and the player is then healed 50 hitpoints.

It can only be made in the Chambers of Xeric with 60 Herblore by using a noxifer with an elder (-), twisted (-), and kodai (-).

This potion is the weakest variant of the overload potions, and cannot be taken out of the Chambers of Xeric.
