I have figured out bard rings in that I usually put Perform, Spellpower: resonance and then insightful heal and slot in a Wizard augment with extra spell points. However, I am trying to work out what would be good for a regular kind of druid as a ring and then also an artificer as a ring as well please.

I usually craft bracers for STR and then a belt for CONstitution with false life, helm is for WIS, goggles for accuracy and usually have the trinket Spyglass (from Crystal Cove) for Intel and search/spot.
