Crit Ring or Magical Ring?

Caveat on Joe's (otherwise correct) math: its a 4 matk difference between the two, so 222 matk is the magic number, which is a bit more conceivable for funded folks. High funding/lots of matk = critical ring is better.

I'm not really sure why using teleport or dark shock would change the relationship between the rings regarding damage though, just talking about the initial calculations.

Dark Shock has 100% Critical Rate with both Rings, so the extra 5% that the Critical Ring gives doesn't actually contribute in that scenario.

I just realised I was missing a line of code in my scenario though so the estimation grossly overcontributes damage from Dark Shock, fixing now. It only requires 357 MATK.
