5/55 rings are really good until high 50s when you can reasonably replace them. I do not think I have anything better on any of my characters. 110 extra hp to a low level silk wearer is amazing. I believe they are around 220-250 each. For some int

I would also save some money to buy gems that you need for reagents for your rune line of spells. This line will save your life.
