Willow
Willow tree
Willow trees are a larger species of tree that are fairly uncommon and are often spotted naturally growing near sources of water. Willow wood is useful as it provides a significant bonuses to bows made from it. Willow wood is known to damage slightly faster than other wood types when used in tools such as a fishing rod, and it's sparsity and long growth time make it unfeasible to use as a 'fuel tree'. Willows also kill other trees within 2 tile of it while growing, due to their massive foliage blocking the sun underneath the tree.
Large quantities of willow trees (ie, forests) that are naturally occuring are extremely rare. JK-H is known to contain one of the only willow forests in the entirety of Wurm.
Arrow shafts made from willow wood damage faster.
