Preservation Chance
This page was last updated for (v1.1.1). |
Preservation Chance is a modifier which allows resources to be preserved when creating items, allowing for the creation of items at no cost to the player. When resource preservation triggers, the player will receive a notification stating "You managed to preserve your resources".
The chance to preserve resources only applies when creating items within a skill, it does not affect the consumption of potion doses, Summoning tablets, or prayer points. Rune Preservation and Ammo Preservation are also separate modifiers, which allow for the preservation of runes and Ranged ammunition respectively.
The preservation chance for all skills is capped at 80%, unless a modifier which increases the cap applies.

Below is a list of many things other than Mastery bonuses and Summoning synergies which provide a chance to preserve resources. Another notable mention is that the Crown of Rhaelyx gains 15% preservation chance (for a total of 25%) when the player has at least one Charge Stone of Rhaelyx within their Bank.
