A quick little mod I made cause I felt the only bow you get from the dark brotherhood really didn't seem like something an assassin would use. Turn undead? Really?!

The only thing changed is the enchant on the bow.

Level 1
5 fire damage
5 sec silence

Level 5
8 fire damage
8 sec silence

Level 10
15 fire damage
15 sec silence

Level 15
20 fire damage
20 sec silence

Level 20
22 fire damage
22 sec silence

Level 25
25 fire damage
25 sec silence

Level 30
30 fire damage
30 sec silence

1500 charge and 150 uses.

I highly recommend you use quest award leveling alongside this as the bow will level as you do.
