Buy RS3 Raw timber fungus soup
Raw timber fungus soup is an uncooked food item in RuneScape 3. It is a bowl of water with bits of timber fungus floating on top. Cook it on a range or a fire to make timber fungus soup. You need level 80 Cooking, and cooking it gives 200 Cooking experience. The soup may burn while cooking.
The cooked soup is a big help in the Croesus fight. Eating it gives the Woodcutting Attuned status. This boosts your Woodcutting work at Croesus but lowers your Mining work. It also adds 50% more damage to the mutated timber fungus skilling node core. That damage boost stacks with woodcutting and super woodcutting potions.
Each soup lasts for one encounter, until Croesus is killed. You can only use one soup at a time. You cannot drink another until the buff is used up by beating Croesus.
Raw timber fungus soup is tradeable and noteable. It is not stackable and cannot be worn. It weighs almost nothing at 0.001 kg, and it is always kept on death outside a dangerous area. Grab some raw soups, cook them up, and hit harder at Croesus.
