+10 crit = 1% crit
At 440 +crit starts suffering diminishing returns.
+20 crit = 1% crit.
At 660 thereis another crit cap where it changes
+50 crit = 1% crit.
There are +60/90 crit scrolls and also if you run w/ a chanter they buff crit as well, so factor either/both of those in, minus from the soft crit cap ( 440 ) and then stack everything into something else ( depending on class ).
