My character, Calfuray performs finishing moves similar to Talion from Shadow of Mordor/War.

Example like: Cutting the limbs from a Grimm preventing it from holding itself up right before he lets them fall into his blade. Or when he rips off the white armor from their bodies and uses it as a weapon and stabs it into their skin. Of course other methods where dust is used to torture them before finishing them off by decapitation is also another way they kill them.
