As a fire mage i am wondering wich rings are better:

Skills Maxed:fire attune, bold and storm

Fire magic +100
Fire attune +5
Fire storm +5
Fire bold +5

firebolt*
royal firebolt is the best, royal of flame (which is 150 fire magic) comes in last

I would rank them:
1. Bolt
2. Attune
3. Storm
4. Fire magic

^ I would place fire storm above fire attunement in terms of priority. I currently use a grand ring of fire storm over a royal attunement, simply because the ring becomes useless if you die and attune is still in cool down (which is like most of the time...).
