Avantoe gloves are a reward that can be purchased with 100 Fist of guthix tokens from the Fist of Guthix minigame. When equipped, the player will get a 50% chance that any herb dropping monster will drop a Grimy avantoe. After 100 drops they will crumble to dust. They require 60 herblore to wear.
They are a great item to wear when killing chaos druids/cave crawlers whilst also having a macaw out for herblore ingredient collecting.
The number of charges used corresponds to the number of grimy avantoes dropped at a time.
