Pretty self-explanatory, but I'm honestly surprised this mod didn't exist already...


    Features:

• Flags the Magic Effect and Projectiles of the two spells as Silent to NPCs.
  
  • Meaning they'll only react to the projectile impacts, just like they do with Bows.
  • For the cast itself to be silent, you need the Illusion perk Quiet Casting just like the Vanilla game.
    
• Adds pseudo, stealth-based critical-strikes to both of the spells!
  
  • You need to have the Archery perk Deadly Aim activated.
  • You also need to be completely out of combat. It's the best I can do to imitate the "stealth" requirement of Deadly Aim.
  • The game will not confirm the 3x damage bonus like it does with Bows. But you can test it on a Chicken or something using console and giving it a million health using modav. Then do the math yourself after a few attacks while in and out of combat. It should be doing extra damage when not.
    
• Limits the in-game audio of the cast to 11dB. This is the sound that YOU hear and doesn't affect game play itself.
• ESL flagged ESP, so it doesn't waste a mod slot!
