Looking at Ade's skills and it looks like she could be fine at 4/4/10
Skill 1 attack buff scales poorly with levels and is little anyway. The range is maxed at 1 anyway.
Skill 2 is just self buff and pierce damage for allies but Grave is better at that anyway so you can save books.
Burst is where the meat of the kit is with that huge attack damage buff. At level 8 is surpasses Grave's level 10 buff.

How does he do it? He gives us sexy bunny girls, saves the game and now saves books too.
