No longer cancels out our Clarity line of mana buffs! No more will you have to worry about over-writing C7 when popping Mana Draw!
(I think I'll actually spend the 9 AAs to get this, now that it's viable. Until now, I'd been sticking with Gather Mana; even though, fully-buffed, I'm around 12.5k mana, 10k is usually enough to top me off if I've just been resurrected. Will be nice to be able to not only top off my mana pool, but also have an extra 5000 mana pumping in over 60 seconds. Would be perfect for MGB'ing C7 or Hastening of Ellowind, and still be FM at the end of the 60 seconds!)
