I've seen a lot of posts for people wanting an unarmed skill line. Well, I've had a lot of glitches/lag when quickly swapping weapons and skill bars (grahtwood cadwells silver), and this has resulted in having no weapon model in my hand but still using the animations for the attack.
Basically, it's given me normal damage unarmed combat! All I've been doing is spamming the weapon change and eventually the model just disappears. Feeling stressed? How about windmilling some mudcrabs with steel tornado? Lots of energy? Wrecking blow a world boss for pure awesomeness. Probably not what you were hoping for, but it's got that unarmed flavour, especially if you tailor your skills to have unarmed style animations. (PS4)
