Do you enjoy immunity mechanic? Does it make the game more fun for you?

The answer is obviously yes. It is a fun mechanic, and makes you think passed your nose.

This leaves -res things still too strong.
They should up lightning res across the board on immunities so that Infinity doesn’t break them, or lower the level of the Conviction. Or rebalance Conviction and Lower Res altogether so that max lowerings is about 35ish%. Same with Amplify Damage and Decrepify. Amp is ludicrously strong for 1pt. At minimum it should scale, not be -100 for 1 point investment. Decrep is overall underutilized, but is really very strong as well.

I don’t even remember the last time I died to one of these.

The only ones that are actually dangerous are the ones that are Cursed. Other than that, they are fluff balls, and newb killers.
