Power and Spells list

• Bat Form: Transform yourself in a cloud of bats and fly freely. This is a toggleable ability (Do not save your game mid flight or you will fall to death when reloading).
  Not required but highly recommended to avoid some known issues with this power I would install this two mods along with Dark-Envoy:
  Equip Enchantment Fix
  Enhanced Invisibility
  
  
  
  
  
  
• Bat Teleport: Transform yourself into a cloud of bats and teleport to the target location.
  
  
  
  
  
• Bat Travel: Select your destination and teleport yourself. You can also mark up to 6 places to teleport to them. (Not all locations are compatible with Open Cities)
  
  
• Dark Hollowing: A beam of pure evil that deals damage over time.
  
  
• Crippling Terror: Paralyze enemies with your gaze.
  
  
• Hideous Mist: Invoke a fog in which you and your allies are stronger and your foes take damage.
  
  
• Ominous Cage: Create an impenetrable barrier around yourself until you disable it. Foes trapped inside with you will be terrorized.
  
  
• Dark Aura: Once a day become one with shadows and resist 50% of physical damage while absorbing the life force of your foes.
  
  
• Consuming Stream: A beam of vampiric power that absorbs health.
  
  
• Shadow Pack: 3 death hounds hide in your shadow and they aid you each time you enter in combat. It's toggleable.
  
  
• Sinister Grip: Deal magic damage and trap the soul of a foe. This effect increases in damage for each soul trapped.
  
  
• Soul Feast: heal yourself, if you have less than 50% of health and have souls trapped by sinister grip spell consume a soul to heal the same amount.
  
  
• Shadow Armor: Resists 50% of physical and magical damage. Is a bit stronger than Ebony Flesh spell since 50% damage resistance is similar to 350 of armor but it also halves the spell magnitude and duration of all hostile spells. This is a very powerful effect, for example this will make your natural weakness to fire from a 30% to a 15%, in general any negative buff will be halved.
  
  
• Dark Envoy: Call the night powers to create an eclipse so you will no longer fear the sun again. This has the same effect as the Auriel's bow with tainted arrows but it lasts longer and you will not have to carry the bow everywhere.
  
  
  
  
  
• The Gate of Coldharbour: Once a day open a massive portal which the legions of Molag Bal can cross. A large amount of Daedra will invade Tamriel. They're hostile towards nearly everyone except the player, so use it carefully.
