Mirror Soul

Your magic comes from the deepest knots in the almost unreal weave of magic. You have figured out how to exploit the persistence of energy to your advantage. Maybe it was a higher being that showed you this power, our maybe it was found after years of research. The power of this persistence gives way to many possibilities, and opens up your eyes to a never-before seen world.

Stockpile

Your knowledge on the persistence of energy allows you to stockpile your energy into a massive onslaught. When you choose this subclass at 1st level, you gain a pool of d4s, you gain a d4 when you miss a spell attack that targets only one creature, when you are hit by an enemy spell attack or when you counter or dispel an enemy creature's magic. When you hit an enemy with a spell attack that only targets one creature, you can choose to reset your stockpile and add the d4s to the damage dealt. Your pool resets to 0 dice at dawn or when you take a short or long rest.

The power of your stockpile increases as you level up. Your d4s become d6s at 6th level, d8s at 14th level, and d10s at 18th level.

Mirror Eye

When you choose this subclass at 1st level, you can cast detect magic at will without spending a spell slot and it doesn't count against your known spells.

Energy Manipulation

You have adapted your stockpiled energy to use it in more creative and manageable ways. When you reach 6th level you can use a stockpiled die in any of the following ways:

• Lethargic Energy  - You may expend one stockpiled die to reduce the speed of any creature damaged by your next spell by 15ft until the start of your next turn.
• Repulsive Blast - You may expend one stockpiled die to push any creature damaged by your next spell 25ft, all creatures pushed this way must succeed a Strength saving throw or be knocked prone.
• Energy Shield - When you are hit you can use your reaction to expend one stockpiled die to half the damage taken.

Chain Reflection

At 14th level, when you damage a creature with a spell, you can halve the damage dealt to that creature and deal the rest to another creature that you can see within 30ft of them.

Energy Sense

At 14th level, you gain the ability to sense a creature's energy without needing to see them. You gain blindsight of 15ft.

Infinite Energy

At 18th level, if you are conscious you stockpile 1 die at the end of your turn.
