Update Notes for Apr 17th

Prevent alpha strikes on spellcasters by letting them start out with protection spells for the first turn. We felt like spell casters could be sniped far too easily in the first turn before giving them a chance to react. Thus, some spellcasters get the ability to cast self-protection spells at the start of combat that only last for the first turn.
