WAR Crit/Rampage build

[Holyomen]

Lowest you can crit is 115% normal damage, highest you can crit is 175% normal damage. Thundaga can break 175% though, but for 58+ (assumed boss level monsters) monsters you need 55+ crit potency/atk power to start criting for more then 115%.

Those percents are showing total crit damage, not additional.
I'll take his research and correct my rough estimation of 50-100% additional crit damage to his 15-75% additional crit damage. And although he did not test MRD/WAR I will assume the results would fall in that same range.

However, seeing that Thundaga breaks the crit limit, it may be possible that Steel Cyclone and/or Godsbane may do the same.
