Shield Bash Force Ring AoO

[SwiftyKun]

Shield Bash Attacks::

You can bash an opponent with a heavy shield. See "shield, heavy" on Table: Weapons for the damage dealt by a shield bash. Used this way, a heavy shield is a martial bludgeoning weapon. For the purpose of penalties on attack rolls, treat a heavy shield as a one-handed weapon. If you use your shield as a weapon, you lose its AC bonus until your next turn. An enhancement bonus on a shield does not improve the effectiveness of a shield bash made with it, but the shield can be made into a magic weapon in its own right.

Ring of Force Shield:

An iron band, this simple ring generates a shield-sized (and shield-shaped) wall of force that stays with the ring and can be wielded by the wearer as if it were a heavy shield (+2 AC). This special creation has no armor check penalty or arcane spell failure chance since it is weightless and encumbrance-free. It can be activated and deactivated at will as a free action.

Let me know if I got this correct.

My character is wielding a 2 handed great sword. He also has on a ring of Force shield. My turn plays out as thus, Free action turn off ring of force shield, full round 2 attacks with greatsword, end of turn reactivate Ring of Force Shield while holding greatsword with one hand(holding, not wielding so I can't make AoO with my greatsword.)

Enemies turn, they do something adjacent to me that provokes an AoO seeing as I only have 1 hand on my greatsword and can't swing it at him. He provokes and I use my ring of force shield as a weapon, shield bashing them and forgoing it's bonus to my AC for the rest of the enemies turn and round until my turn comes back around. Repeat previous steps.

By the rules it's correct.

Although I'd expect some DMs to disdain it. The free action grip change faq has its critics.

Seems good by rules.
