Which level 20-29 adept 3 is the most useful?

Hello,I'm having a hard time deciding what spell to upgrade. I have Wards of Shadow Master 1, I have Ancestral Ward Adept 3. I'm trying to decide which spell will help me the most as a soloer.Should I go with Miasma (currently at adept 1) or Cold Fire(at adept 1), or go with Propehtic Guard (currently at adept 1) ?I am loath to go with Wailing Haze as it is only 5 more levels for me to reach 35, and get Howling Haze.Any suggestions for soloing ability?

<DIV>Huh.  Well, what I'd do is watch the spells I cast and upgrade any spell that I cast on every mob.</DIV> <DIV> </DIV> <DIV>Perhaps Cry of the Ancients?  Good against multiple targets.  I dunno.</DIV>
