Stoneskin is really the only thing you really need from conjurer. Foresight, Blood Bath and Mercy Stroke should all be on your bar (all from marauder).

After that, it's.... MEH. Protect is only useful if people are dying a lot in content as your healer handles this at the beginning. Un-traited Fracture is a DPS loss (and kills more TP on a class that floors TP in 3 minutes), but it can be useful in highly situational scenario's.

Clemency is much better than cure, non battle raise is pretty pointless, and skull sunder is simply sorry as you can't combo it.
