One thing that players of necromancers should be aware of that differs in 3.0 due to the change in the ROC spell <cyclic instead of harnessed mana> -

in 2.0 you can virtually keep the spell up forever as long as you could harness mana for it.

in 3.0, if you walk into a room which is magically null <either from being created that way originally - such as the crossing bank, a few other rooms like that> or a room which is "created" to be so by a certain clerical spell - ROC will dissipates, leaving your aura naked.
