The trait Quick with a Blade in The Martial Champion trait tree removes the health threshold requirement of this skill.
The trait Merciful Minded in The Berserker trait tree increases the health threshold requirement and at max rank causes this skill to always critically hit.
Being one of the few fast skills in the Champion's arsenal, Merciful Strike is best used immediately after skills that have a short animation (such as Swift Strike), or immediate skills (such as Clobber). Having no off-hand component, this skill deals more damage with a two-handed weapon.
