Mercenarie Attacker

Hi, i saw that mercenarie attacker choose many times with finale but when find in youtube about mercenaries skills, saw that skills with boost crt always hit any boss.

For example this is my mercenarie 2h

Enchant and Buster have buff crt in 2h and i tested before in ornlarf where always hit with the skills and pyxtica green mode with the same results.

I like the merce 2h because do good damage and fast that a magic merce.

Is probably that skills with crt will be perfect aim?
