Never seen anyone parry with bare hands before:

Due to the contre skill adding +10% chance to parry.
This also makes me believe that no attribute increases parry chances. Since I've never seen this before without the contre skill, and low agility brutes parry as much as hyper agiles. As well as Hyper agiles parry as much as Stength brutes. Though Strength does increase chances to disarm.
Shield +30%
Contre +10%
And with good weapons that add on to parry like Sai, Baton, all the swords, frying pan, etc.
This has become one of the best defenses for Muxxu.
Though Choc (impact) still is able to disarm even if blocked. Becoming a more important skill to also have now.
