Guild Wars 2

A quick question:

With 150% critical damge, do I deal base-damage x 1,5 or base-damage x 2,5?

It is a raw stat and not an increase, so as opposed to normal 100% base damage, when you crit you do 150% base damage, so base damage x1,5 (given you do not have ferocity that increases your Crit multiplier)
