I know we can't use these and my idea will never fly, but here goes.

Huggy thinks '::hugs'n'smooches::
Barbarian meditates Smash Huggy gweth
Barbarian slams his HB/MB into his own head smashing his own gweth, getting a 20 second or more stun and taking moderate to severe internal head damage.
Huggy's gweth is smashed.

I am all for a move that requires us to be in the same room and - using a melee weapon mind you - can smash their gweth.

Something to the effect of...

Galren approaches Navak and stares him directly in the eyes. Before you can even blink Galren draws his katar from his rucksack and slams the flat edge of the katar against his temple shattering the gwethsudan.
[Roundtime: 5 seconds]

Navak is stunned!

Messenger Boy: The Thessalonian you're fighting... he's the biggest man I've ever seen. I wouldn't want to fight him.
Achilles: Thats why no-one will remember your name.

Perhaps a special merchant selling magic-nullifying hammers shows up and lets people purchase one, and when in the same room as them, a barb can make a normal attack contest with blunt weapons to shatter gweths specifically or rings specifically. (can't attack head and hands all at once). After the hammer has absorbed enough magic (similar to charges in a gwethsmasher), it becomes a crappy MB weapon.
