Am i crazy or is "Petrified Rock" the greatest Relic in the game?

[Paro]

I got it by accident by blowing up some rock. And wow. You can basically sustain yourself the rest of your entire run just by blowing up rocks. It's like everything you could ever need --including even more relics!--just pops out.

Yeah, it's definitely one of the better relics in the game. I wouldn't say it's the best since it's possible to be fine without it, but it certainly makes the run a lot more interesting and fun.
