A curious note: the MP bonuses from both tanks are additive, which can be proven by equipping the mana tank, noting the amount of mp gained, then comparing that to the mp gained by equipping and unequipping the mana tank I with mana tank II equipped. The percentages however are approximate and seem off by a bit.

i noticed after the march 2010 update that i got 4mp/tic on my 56 pup using the whitemage head and stormwaker frame. but when sync down to lvl 14-17 i got only a 2mp/tic same head same frame. tested many times
Yeah. I've suspected that the amount of refresh (and probably regen as well) would vary with level. I'm synced to level 45 right now and only getting 4mp/tic with both equipped and 1 Dark Maneuver, so it seems it is affected by level. --GarudasWing 23:58, March 28, 2010 (UTC)
At level 57, I get 4/6/8 MP, so clearly it does vary with level. --Elwynn 15:16, August 25, 2010 (UTC)
