Searing ashes detail

Searing ashes are the 100% drop from lava strykewyrms and their boss variant. They grant 200 Prayer experience when scattered, 700 prayer experience when used on a gilded altar with both incense burners lit, and 800 prayer experience when used at the Ectofuntus. They can also be used to fill infernal urns.

Searing ashes give the most prayer experience out of all ashes, giving more than twice the experience of tortured ashes.

Searing ashes are the secondary ingredient needed to create Aggression potions, requiring 82 Herblore.
