Grimy irit

A Grimy irit is a herb that has not yet been cleaned to make a Clean irit. Grimy irits may be grown from a irit seed with a farming level of 44. It is dropped by certain NPCs. Cleaning a grimy irit requires a herblore level of 40 and gives 8.8 herblore experience. Clean irits are used to make super attack potions, super anti-poison potions and super strong anti-poison potions with herblore levels of 45, 48 and 79 respectively. Grimy irits can also be obtained from the Sorceress's Garden activity. They spawn inside the Edgeville Dungeon in the Resource Dungeon by the Chaos Druids.
