Magic critical chance %


I check the magic critical on the files with Wild magic lv2, POW, Siren, Scepter (hero wep) and i make like 20-25% magic crits.
May I ask what is the magic crit chance for every buff above and if there is a cap % for magic crit like other late chronicles on files?


So i found this for the pow:
Magic crit rate val = 2 (100%)
2nd image is for wild magic lv2:
magic crit rate val = mCrit
and above there is a table 3 and 4
3rd and last image is for dance of siren:
magic crit rate val = 3

So if pow val = 2 = 100% how much is val 3 and 4 = %?
