Quote from heretic304;255916:
Critical hit % here can go well over 30% though, so I doubt it follows the Mabinogi style. Look at spear lanns, for instance. They have 20% from Critical Hit r7 and 22% from Fury Infusion. From what I've gathered, crits are equally likely to happen to all monsters, whether boss or not, so there's likely no Protection stat.
confirmation on no protection stat: it's widely known that monsters only have defense, but damage reduc is more calculated by % rather than flat like defense was calculated in Mabi.
Regarding OP: I'm not sure, but I have a way you could try testing.
most weapons give ~20% crit (more if you upgrade past 5 but we can't so w/e). You get 3% from 180 will, and then as you said 20% from crit r7.
If weapons bonus % is additive, you should get about 43 crits out of every 100.
If not, you should get something lower. It shouldn't be too hard to test.
For those of you wondering: Will/60 = bonus crit chance from will.
