Shadow Talents is a mod that touches on some powers that may have come from shadow magic lore and some of my own ideas. It's mainly useful for a physical fighter but any build can find use in at least one of the powers. The powers don't use magicka to cast but instead it uses either stamina, health, and cooldowns. Shadow Talents will allow a player to hit ranged fighters without a ranged weapon, close down large distances for a surprise attack, and briefly enter a shadow form to negate all damage.
I mainly made this for a character class build but decided that I'd expand a little and then upload it.

Dark Step - When in the shadows, you can leap out a short distance. Costs 30 stamina.(similar to a blink spell)

Shadow Shift - You enter the form of a shadow to negate an attack. 10s cooldown.

Form Shade - Create a Shade for 45 seconds wherever the caster is pointing. The Shade drains 50 health when it kills an enemy and gives it to the player. Costs 75 health.

Shadow Reach - Use your weapon through the shadows and hit foes at a distance you never could for 15 seconds. 20s cooldown.(similar to Kenshi from Mortal Kombat)

Acquiring:

In Silverdrift Lair, there's an enemy that will need to be killed by the player. Once killed,In my characters story it'll be a random chance encounter, I was going to leave a note somewhere the player will stumble across but I decided against it and left it open ended.

Requirements:
SKSE

Other:
At night, you can Dark Step while in a shadow cast by the moon, but not out in the open.
A well timed Shadow Shift can negate most of the damage from dragon breathe shouts.
Form Shade levels with the player so the amount of enemies it can kill will go up while the requirements and draining is still the same.
Shadow reaches distance is based on stamina and health. Higher values means further reach. Capped at 30

Known bugs:
Dark step only works if the game considers the player to be in the shadows. Sometimes, visually it looks like you are in the shadows but the game
doesn't consider it to be. Don't worry though, it won't cost you any stamina.
Please report anything you find.
