Overview
Use mobs to dig for you, especially Gronk. The pug-looking-raptors are especially good at this and much safer. Other mobs are okay.Build walls defensively against projectiles and bosses. You can also build furniture in unreachable areas, such inside a tree and above, or stairs underneath the ground using wooden floors or walls. The ranged pug-looking-raptors also seem to struggle and sometimes completely miss lower-elevation furniture such as crafting tables.Good luck!
