I am trying out tree farms, and having a harvest dilemma. TNT wont break wood. Imo, dispensed TNT should be allowed to break naturally generated blocks, such as trees planted as saplings, but that's besides the main point. So that brings me to this question, will a caged wither harvest wood? My arms are super tired and I cant hold up that axe anymore
No, I tried to do this a while back. Withers can not break wood if aiming at a passive mob such as an iron golem. Unless something has changed, this will not work.
