At some stage, it was suggested to me I buy a 'Haunted Ring of Force' as it would help with Mana. Best advice ever! I don't need to pot mana very often anymore. However the rest of the ring specs aren't super, and I'd quite like to upgrade to something else. But is there anything else I can do that will match the m/s of the haunted ring of force? Doesn't have to be a ring, but I'd like something that does the same job.

On a side note, what does m/s stand for?
