My better half has started playing DDO as a wizard and is getting really worried about gear and maintaining all the different stats for her different spell types. As I run Acid Warlocks almost exclusively, I haven't been terribly much help, but I'm trying to assist her with setting up some practical limits around how many and what spell types she should maintain.

The bulk of the gear she gets with spell power boost is on weapons, rings and armor, so she could juggle five different spell types. Being a Pale Master, negative/null is a must, but beyond that, how many different spell types should she reasonably be trying to maintain? Are there any she should just forget about? She isn't warforged so Repair/Reconstruction seems low priority and there are few Arcane Positive/Devotion, Light/Radiance and Sonic/Resonance spells so my inclination is to steer her clear of those.

Suggestions?

Thanks in advance for the feedback.
