# The Wise Oak [[The Wise Oak]] is a unique [[Bismuth Flask]]. ## Mechanics This flask provides a defensive buff to whichever resistances share the lowest uncapped value, and a penetration buff to whichever resistances share the highest uncapped value. If any or all of your resistances match, they will share benefits. For example: - Fire res: 120, Cold res: 120, Lightning res: 110 In this scenario, you gain the penetration bonus to Fire and Cold because they are tied for the highest value. Lightning will get the defensive buff. - Fire res: 120, Cold res: 120, Lightning res: 120 In this scenario, you are in fact getting the offensive and the defensive buff to every element.
