Chaos Mage

The Warp is an opposite dimension to our own made up of pure and unrestrained magic. Within this realm there are deities that spread there influence around the world granting slight bits of there power to the mortal that roam our own realm. The wizards among those followers are known as chaos mages. These mages are often known to either lead or reinforce the armies of the chaos hordes from the war of rage.

Overcasting

Whenever you cast a spell that has a spell attack roll you can choose to overcast it. 

When you overcast a spell you can add 1d6 to the spells damage up to the level of the spell. So if a third level spell is cast you can overcast up to 3d6 damage extra onto the spell. However for every spell level you overcast you have a bigger chance to miscast by adding the level to your critical failure possibility. 

So when you overcast up to 2nd level you will roll a critical failure on a 1 and a 2. When a critical failure is rolled you take the overcast damage yourself.

Master manipulators

Everytime you cast an Enchantment spell were someone else has to make a savingthrow they take a -1d4 to there savingthrow.
