incorrect. the only useless skill i see is the one that recovers like no health oh and removes fatigue from shock.
Mana Capriccon is a great long invincible frame and ignores red attacks.
Inspiration is wonders when you want to burst damage and burn through stamina.
Mana Agrement not only gives good Mana but also gives good SP too, AND if you use the ASD Mana Agrement it does stupid damage and restors the lost sp you used to use it.. I play without using mana bis in the beginning till i get to 10 stacks, i dont go into mana bis till im at full mana, till then i snap at 10 and ASD Agrement. I use Receding interlude almost after every 3rd hit to keep myself far enough not to get hit and close enough to be in range to land attacks and it also counts towards your stacks and is good for skipping animations to get ready for snap faster.
Fierce Rondo is perfect for clearing mobs fast even though you can gather mobs together and Enhanced Mana Agrement and one shot most regulars.
Stringendo Strike i use if someone is holding the boss or if the boss flinches and really its more viable to use it in mana bis mode.
thats pretty much how you secure a high position on the dps chart though..
I was experimenting with changing between mana bis with 20 stacks and crit for 97k against Agony and Despair with only 24k M.ATT
