Coffin Lid and wind up Echidna too rare?

Not true at all. People have posted their statistics on previous pages and they saw around a 2% drop rate. I've personally seen it once in about 70 runs. It's much, much lower than Puff and Onion originally.

That also has a lot to do with RNG. The drop rate could be 5% or higher and you'd still never see it. lol. RNGesus is all in this game.
