What do you find as the most useless and most useful staff hex?

[team black aumbu]

flaming skull and wither are good desilation is ok for the wow factor and desolation is ok if you have 5 points it would do alot of damage. i hope this helps.

[Poison elf]

Flaming skull is most useful.
Desolation if it remains on this fast cast, is great now. (look at glitches)

Banish and Pestilence I would go with as more useless.
Putting a 5th point into spirit mastery,,,most useless.
