i generally ignore the existence of those spells. Their wording is problematic, and as Mage especially in blacktrench coat you really don't want to be identified as a mage, or have anything to do with melee combat (Leave that to the bullet sponges). So running around with a lightsaber is ideally to be avoided. My recommendation would be to stick with a single target and an aoe indirect spell, (Pick your preferred element), if you feel like you need another combat spell, the grab stun bolt. Then stack the rest of your spells, with utility (Heal, Levitate, Improved Reflex, Armor, Improved Cha, Improved Will, Improved Invisibility, Mind probe, forget, etc). It's often fun to save a spell slot or two for spells that say something about your character. Maybe that's Fashion so you make a fresh new look everyday, or one of the illusion AoE types that you use to great effect at parties, but something fun. Make sure you have sustaining focus improved Reflexes or another method to keep it up, and consider if you want to invest in any other foci.
Given that he is cha primary, it just fit well, Skill group have issues, in that you can't spec them in generation, and I avoid breaking up high numbers. But it's true you're not the face. Generally accept wisdom says most characters should pack some level etiquette and con. But it's not critical to the build outlined, so if you have another preference feel free.
