Holy overload potion

The holy overload potion is a six-dose combination potion that can be made at level 97 Herblore after buying the recipe for coins from Lady Meilyr (you do not need to find this recipe in Daemonheim). It is made by combining an overload (4) with a prayer renewal (4), giving 350 experience.

A dose of holy overload has the effects of both an overload and prayer renewal, boosting all combat skills by 3 + 15% while also restoring prayer points at a constant rate for 6 minutes.

This can be a highly economical combination potion to make. Each flask gives 6 doses with an input of 4 doses of each potion, and there are few situations where one would want overload but not prayer renewal. Using holy overloads also cuts the inventory space needed in half. Each flask lasts for 36 minutes total, so plan accordingly.

Trivia

 * This potion's name was originally Renewal overload in the design documents.
