Solo builds that don't involve being necromancer?

[Anraas]

I know there is the pyro/SC/Chloro one. I just don't got the gear for it (my mage is a fresh 50.). I really am not a fan of pets, so I was curious if there is anything else out there?

Chloro warlock

If you don't like pets then tank yourself up with this template: http://rift.zam.com/en/stc.html?t=0z_Rq..VdIo0h.Vx.-6

That gets you a big boost to effective HP and self heals (and moderate group healing too if you stick to life damage)

Leaving you 38 points for a third soul. I use 38 pyro with it for spark & flicker. You might want warlock for even more HP and life regen spells.

If the OP is relatively freshly geared (very little in the way of raid vendor pieces), it's difficult to justify using something other than chlorolock (SC/pyro/chloro is definitely one of the better ones as Zyzyx indicated, but it's quite gear-dependent).

Chlorolock will give you a sizable health pool (21 percent of intelligence as endurance from chloro + 10 percent max health from lock + 40 endurance buff from lock) and can be adjusted to give a newer 50 some nice survivability options (a mitigation cooldown, a temporary health buff/self heal and two good instant self heals from chloro). It's just a little slow for AoE grinding since Devouring Shadows is meh since they got rid of double ticking with stopcasting.
