how long are u fighting voa mobs or named
This is a bit wrong. It *will* work on spells > 85, but you don't get the full 100% mana reduction. You get 5% less per level above 85 to a minimum of 50% mana reduction for level 95 spells (and any above that, in the future), just like any other focus degredation. Depending on your spell lineup, it can come out to about a wash vs using one of the mana barrier/recovery clickies. It also doesn't work on instant spells as well as the Ethereals.Its the raid ones, you could one group that Korafax demon raid (can't remember the mobs name) to get it.

And I'm wrong its not 1 mana cost, its 0 mana cost, not a big difference lol, but thought I'd correct it. It does work for spells > 85 long as they are not ethereals. You want to try to use your instant spells with that as much as possible and since instant spells are on same timer I do a weave of thrice with instant line, and if GoM procs or the dmg buff from Thrice procs, then I use ethereal right after.
they cost 400 to 600ish mana to begin with
to be honest the mana saving is not that appealing for low mana cost spells so it must be something else that makes the bp effect attractive, ie not saving mana on low mana costing spells
i just want a good dps line up mana aside besides chaining ethereals (fire ice)
I chain all 3 havocs first (hope for twincast proc from one of them). You can start them early on a mob, after their cooldown starts move to Concussion right after, if Twincast (the spell, not the proc from havoc) is up , use Twincast, if not move onto the Fire/Ice/Magic Ethereals. Fire first then cold if both are on cooldown sometimes magic will go off, but usually you end up just chaining Fire/Ice.
If mana is an issue for you, use what others have posted, but the above should give you close to maximum dps.

Also, havoc spells have a chance of refreshing themselves instantly I think, so theoretically you could have a chance of casting 6x havocs if your last havoc refreshes the 2 previous ones you cast, increasing Twincast chance even further.
