Daily Punch 7-16-14 Stealth Spell feat for DnD Next

How about a Stealth Spell for DnD Next?  How about a wizard/rogue hybrid?

Stealth Spell

Up close or hidden, you know how to stick an enemy with a spell when they don’t expect it!

Benefit: Gain the following benefits:

1. When you cast a spell when hidden, all enemies have disadvantage on the saving throw or you have advantage on the attack roll.
2. When you cast a spell in melee that requires you to touch an enemy and you and an ally are engaged with the target of the attack, you gain advantage on the attack roll.
