Battle Aura

The Spell of Battle Magi Wizards. Being able to cast this spell makes you a member of their Wizardly Order. And if you don't join they'll hunt you down for learning their magick and force you to join or forget the spell from your list of usable spells. 

This spell gives you a +1 bonus to your AC. This Bonus is natural in nature and lasts in an antimagic zone. Also this spell gives you 5d4 Temp-HP and the spell lasts only as long as you have that Temp HP. If you lose it the spell is over and the effects are undone. It also gives you a +1d4 bonus damage to your unarmed strikes, the spell mage punch, and weapon damage. Again this bonus only lasts as long as you got the Temp-HP. Lastly this allows you to cast Shield at the cost of one Temp-HP and maintain it as if it was a concentration spell if you know that spell as well.
