This is what happens when you have a Skeleton XP farm.
You can combine the bows to put their durability into one bow.
Okay, good. Because a bunch of weak bows wouldn’t do me any good. Though I think the bow I’m using won’t break any time soon, since I only use it for Skeletons (well, sometimes I use my sword, and sometimes my bow) and Witches and fight everything else with a sword.
