Rise of the Thrall Lord
Gloves of Greater Spell Disruption
If you hit a creature with a melee attack while it is casting a spell, add 5 to the DC of the Concentration check required to avoid losing the spell. If you strike or grapple directly with the gloves, add 10 to the concentration check.
In addition once per day the gloves can dispel magic and spell like effects using a Greater Dispel Magic spell. The effective caster level of the dispel is equal to the BAB of the wearer.
The dispel effect can be triggered in one of two ways. First using a successful touch attack against an enchanted creature or object. Second, the wearer can bring his hand up defensively to dispel spells directed at him or that he is in the area of effect of. Using the second method requires the wearer to forgo a saving throw and rely on the gloves.
