>Does Renewal help at all with aging due to wither?

I forget the exact specifics, but I remember that Renewal does a lot to help with wither in general (i.e., including strength loss and maybe even damage).

Edit: I looked up the specifics and it's both damage on wither and the stat loss, including -DEX from Languor of Aeons, if relevant. (In general with Wither, how much STR you lose determines how likely you are to lose years, or if you even can lose years, so indirectly it's a huge help with that too.)

Somebody should start adding this stuff with citations/links to the wiki as I spew it forth.
