Level 1 summons 3 fairies for one minute and their max hit is 70. They miss a lot. Not impressed so far. But test continuing...
Level 4 max hit 180.
Level 6 max hit 285.
Max Level 9 max hit is 440.
In one minute of life the 3 sprites did a total of 27,398 damage to a guildhall practice dummy, attacking from the back (no ripostes or parries.)
Landed hits 82 times and missed 60.
DPS is comparable to maxed-out Nature's Guardian, the 1-minute BooBoo Bear AA.
In terms of mana-free AA-derived druid DPS easily the best return is for maxed-out Storm Strike which can crit for over 90k and can be recast every minute. Nature's Guardian and Spirits of Nature take a distant second place. In terms of which to buy first, it's a tossup except Spirits of Nature maxes out at 9 levels, as compared to 24 for BooBoo so the first is much less expensive in terms of AA investment.
Mana-free damage is ALWAYS worth acquiring. But I would encourage all druids to buy STORM STRIKE as soon as possible and keep it maxed as they level up... the other two AAs should be bought MUCH later just because they cost so much to maximize and even at max their damage is not impressive.
