ToME: the Tales of Maj'Eyal

Any tips on which aura to focus on as a mindslayer? I plan on going caster heavy so the physical one seems tempting but if lightning resistance is rare outside the storm quest line the lightning aura may be more effective. Any opinions?

My favorite is Charged Aura. The spike effect is a chain lightning which, if you invest heavily in the Focus tree, is very powerful. Heck, it's powerful even without any points in the Focus tree.

Does anyone know if conduit works on a gem focus? will it smash people for the aura damage?

Conduit should have no effect on a gem in the psionic focus slot.
