At the current availability, using the ring of mara, consumes one of your available jewelry locations, sacrificing both your partners, and your own stats. If they allowed this ring to be a specialty piece, allowing you to keep this ring on at all times I believe people might use them more regularly, even into end game content. Also along the line of a specialty "item" slot, they could create a ring/item that one could equip that would say, increase your drop chance of weapons from chests and or mob's, or another for clothing pieces. Fishing, make two drop instead of 1? Possibilities of these special rings could be endless. Make them acquired via a quest reward so each character has access to them?
