The following made me weary:
Also Elemental Empowerment (genasi wizard): add Str mod to damage with acid cold, fire, lightning, and thunder wizard powers.
Which you can combine with:
Sorcerous Power- requires paragon mutli as sorc- gain a bonus to the damage rolls of arcane powers equal to your Str or Dex modifier, +2 at 21st.
Elemental Empowerment is a bit problematic as it allows a Wizard to have damage that is closer to Striker Dmg, at the cost of having to chose a very specific race.
I am less concerned with people stacking it with Sorcerous Power. For 1, the table description of Sorcerous power (and several other multi class feats) is wrong.....which will deter many people.
Secondly, Paragon multi classing to be able to add you STR or DEX modifier could be a down grade in power compared to Std Paragon Paths. You miss out of bonus abilities and effectively lose feats to emulate class powers. STR is a waste of a dump score for Wizard. Now Dex is Pre Req for so many good Wizard Feats it is the logical option, but again with so many interesting feats w/ high Dex Requirements, spending 2 feats to M/C w/ Sorcerer is more of a problem.
Did anyone else notice that one of the Familiars grants you the power to speak "Infernal".


Of course Supernal is just a lame name.
