Shadow

The Shadow is a melee dex-based spellcaster that has a hit die of 1d8 and cannot be multiclassed.

Light Armor Proficiency

Ability to wear light armor. Also grants dexterity saving throw proficiency.

Grasp of the Shadow

Ability to cast spells only in melee range, but grants the ability to attack with your offhand weapon with no bonuses to damage as an bonus action.

Extra Attack

When you use an action to cast a spell or make an attack, you may make an additional attack with your main hand weapon.

Energy Transfusion

Twice per long rest, you may take 1d4 damage to regain that many level's worth of spell slots. For example, if you take 4 damage, you may regain a used 4th level spell slot, a 1st and 3rd level spell slot, 2 2nd level spell slots, etc.

Obliterate

Once per long rest, if an action is used to cast a spell, you may cast a second spell of a lower base level at its original spell slot level. For example, if you cast Fireball at a 9th level, you may cast any 1st or 2nd level spell at its base level (i.e. Level 1 for Magic Missles). If you do, gain one level of exhaustion.

Advanced Energy Transfusion

You may now use Energy Transfusion three times per long rest rather than twice. Additionally, regain 1d6 worth of spell slots rather than 1d4.
