Hello,
1. The Allagan Caster and Healer Robes have this nice Crystal on a chain. I was thinking, why not make them pulse/glow like in FFXI? It would look great!
2. Give them an Aura activated with Crystals|Clusters. Say, 30 Minutes for a Cluster, just like food. Make it a faint Healing potency buff for Healer and a Magic Damage Bonus like the SCH fairy for the Caster Robe.
Cheers
