I checked MIC (Magic Item Compendium) for ideas. Up to GM decide does he allow use 3.5 sources in Pathfinder game :P.<br/><br/>I thinked Gilbert's ring would have Ring of Communication effect for now (the ring costs 2,000gp). It works so that he has two-way communication at-will to all heir rings connected to his into 1 mile radius. This case the half-sisters rings are connected already to his.<br/><br/>What comes for Rose.....my personal vote would go to add permament 'Protection from Evil' onto the ring. As CL 1 effect. It gives +2 deflection bonus vs evil guys, protection from mind-effects from all sources and summoned monsters cannot touch you. It costs 2,400gp.<br/><br/>But if think actual item effects from MIC;<br/>Ring of Counterstrike (works as ring of same name; 2/day allows as AoO strike enemy who failed hit you)<br/>Ring of Revelation (Allows at-will as standard action detect are folks evil outsiders or undead with 1 round lasting aura glow, working same as detect evil)<br/>Ring of Desperation (3/day get +30'ft land speed and +5 dodge vs AoO as swift action when your less than <50% of HP)<br/>Ring of Translocation (2/day teleport 10'ft as swift action)<br/>Dimension Stride Ring (+2 jump, 5/day 60'ft teleport as standard action)<br/>+5 to one skill ring<br/>Ring of Fortunate Striking (allows re-roll attack roll 1/day)<br/>Ring of Throwing (3/day allows grant melee weapon throwing and returning qualities)<br/>Ring of Battle (3/day +2 bonus to special combat actions like disarm, sunder, bull rush, trip etc)<br/>Ring of Brief Blessing (1/day allows your weapon/unarmed strike treated have both good and magic qualities for 1 round)<br/>Ring of Four Winds (4/day allow +2 AC vs single attack or gain feather fall effect)<br/>Ring of Weaponry (Allows store one weapon inside the ring)<br/>Ring of Resistance (+1 to all saves)<br/>Ring of Teamwork (+3 bonus via aid another when you or ally does it to you and if flanking with ally, ally gains +2 dmg rolls vs flanked foe and also 1/day grant +5 competence bonus to AC to you and ally adjacent to you for 1 round)
