^ ya he right it gib Max SP +15% n__n
Yeah it's enough, it's much harder for when you ND PVP though, since you practically don't get any useful SP bonus. That's when Hollowring comes in, which takes a slot for a defensive card in your cloak. Some go 1 FBH/1 HP/SP card for shoes, not the max damage you can have but if you need your SP, then why not. Improvise.
For an ND Sinx though you can have 2 FBH, just have at least 100 SP for casting EDP.
