Useful trick for new players that, like me, struggled to fight the incredibly tanky golems when visiting the Mountain biome for the first time.
The only type of damage they are weak to is from pickaxes, but normally the pickaxe is almost impossible to use as weapon since most of its hit detection is focused at your feet so the only way to reliably hit an enemy with full damage is to be standing on their head. Luckily, Stone Golems have a nice large, flat head to stand on if you can just get yourself on an elevated position to jump onto them.
Aside from keeping your footing, the only thing you have to bear in mind is what type of golem it is. If they have the spike hand like in this video, they're pretty much helpless while you're standing on their head, but if it's the other variant that has just big boulder arms, they CAN smack you off with any of their attacks but you can avoid that by just jumping straight up between getting in hits with your pickaxe. It takes a bit of practice and you will fall off from time to time but getting the hang of it you'll find it's pretty much the fastest way to kill these things.
Made testing the feature in Steam Record that lets you clip video playback before saving/exporting.
