So in Stonegarden, I met this prick Skeleton called Crispin who challenges us to a battle of philosophy. But the only way to answer correctly is to use your Tag responses, but you have only two tags and there are three questions. If you get even one "wrong", you die.
Also, he's got some kind of invulnerability aura. I tried murdering him for being annoying, but even though his health is 0 he won't die, he just keeps teleporting around randomly when hit.
So I went back and told him to stay buried. But he keeps asking everyone who is remotely clear to dig him up, and the interruptions piss me off.
So now I want to cover his grave in a thick layer of concrete so no one can hear him or dig him up again. How do I craft the concrete?
