The skill says "Deals a critical chance attack and reduces damage taken until next turn."

My question is if this is a set number, or if the Critical % the character normally have is added to this skills Critical chance. Does it for example synergy with the "Combat Skill [passive]" skill that the Knight have, that add Critical to the normal attack?

If you go only on the current wording on the skill, it should NOT add the normal Critical %, but it would make alot more sense if the normal Critical % number would actually be added to the skill.

So, is this an error in the wording, or does the skill ignore the normal Critical % entirely?
