Spell Marshall

You have attuned your body and mind to master spellcasting in the heat of battle. 

Spell Frenzy. Once per turn, when you Cast a Spell that has a Casting Time of 1 action and requires an Attack Roll with a Melee Weapon, you can instead choose to change the casting time to 1 Attack for this casting. 

Quick Focus. On your turn, if you are concentrating on a spell, you can cast an additional concentration spell. At the end of your turn, you instantly lose concentration on the spell you cast using this feature. Once you use this feature, you cannot do so again until you complete a short or long rest.
