I'd like to create a non pale master, warforged trapper/wizard build that can potentially solo (Or contribute) through to epics (I'd settle for EH solo'ing but I'd like to contribute to EE end game content).

I have a TR'd toon with 3 lives I could use (2 lvl Cleric, 1 lvl rogue.)

I have a few questions though :

1. Should I get two levels of rogue for evasion and trapping/opening/search skills (But potentially nerf spell DC's) or should I just go 1 level artificer for the skills and not take as big hit to DC's?
2. With the two levels of Conjouration will using Power Word Kill as my main insta-kill be effective to end level?
3. What spell school should I be specialising in?

Any basic advice or hints on how to play an effective wizard?
