Hooookay...
1) No, I have not yet found anyone in Torden who will recharge this ring. As far as I know, there is no mob quest to recharge it.
2) This ring, like most post-Luclin stuff, is NOT rechargable via any combination of mana batteries, tool kits, or tinkering bags. I could be proven wrong by a gnome with over 250 tinkering, but if you've got the cash to get tinkering up that high, you've got the cash to farm a new fully charged ring :P
3) The stats on this ring SCALE DOWN with your level. Therefore it may or may not be the neatest thing to put on your lvl 10 toon as far as stats go.
4) The DS on this isn't great and there's two charges of it. Pay a shammy to make Skinspikes I-IV for you, it's easier. Heck in the time it would take you to farm this ring, you could probably PL your own shammy to 25 and start making your own skinspikes potions.
5) It doesn't take any more time to whine for a high lvl druid to toss spikes and regen on you than it does to stand around and whine for Temp. This too may be a better option.
