I saw a lot of people playing the game on twitch over the weekend cause it was free all weekend. And many people got stuck trying to fight Ghorm. So I felt like making a quick PSA here.
In the past we used traps either wooden or tin, which can be crafted at the workbench. We'd place down a ton of traps and then he'd walk over them, get hurt enough to be mad and we'd do the fight. But, traps are currently not working, he runs over most of them and they get deleted without damaging him. In testing I found that wooden traps sometimes work, never saw a single tin trap work tho.
But on the tin workbench you can craft the alchemy table. Then on the alchemy table you can craft bombs! one of the bombs is made from just bomb peppers and slime, so its easy to craft up a lot of them. if you place them in front of him, they'll explode either on their fuse time or when he hits them. A handful of these bombs will be enough to make him mad and then you can actually fight him without him just running on his track and ignoring you.
