Shadow Knight

As you have learned your magic through the darker side of cities and the line between law and chaos, you have the touch of darkness it self

You have an innate connection to the underground and lawless parts of populations, as well as respect from most magic focused rouge guilds.

Gathering Shadows

At 2nd level, you have learned to gather the shadows around you into your magic to fortify yourself against harm. When you are hit by an attack or you fail a saving throw in dim or no light, you can use your reaction to gain a +2 bonus to your AC against that attack or a +4 bonus to that saving throw.

You can only use this feature three times per encounter.

Shadow initiate

Starting at 2nd level, your eyes become enveloped in darkness and glow a dim black. You can give yourself a bonus to your initiative rolls equal to your Intelligence modifier, and gain a darkvision of 60ft.

Dark Well

Starting at 6th level, you can store magical energy within a black well deep within your soul to later empower your damaging spells. In its stored form, this energy is called a Dark Well.

You can store a maximum number of power surges equal to your Intelligence modifier (minimum of one). Whenever you finish a long rest, your number of power surges resets to two (unless you finished a long rest with less than two points in which it will reset to one). Whenever you successfully end a spell with dispel magic or counterspell, you gain one power surge. If you end a short rest with no power surges, you gain one power surge.

Once per turn when you deal damage to a creature or object with a wizard spell, you can spend one power surge to deal extra force damage to that target. The extra damage equals your wizard level.

Invisible Protection

Beginning at 10th level, the twilight you channel helps ward off harm. While you maintain concentration on a spell, you have a +2 bonus to AC and advantage on constitution (concentration) saving throws/checks.

Fending Shroud

At 14th level, your Gathering Shadows becomes infused with powerful necrosis. When you use your Gathering Shadows feature, you can cause magical darkness to arc from you. Any creatures of your choice that you can see within 60 feet of you each take necrotic damage equal to your wizard level.
