there could be stronger weapons in TESV or as strong
No, this is really overpowered compared to most weapons there have been available on the past TES games, and could break the fun of collecting loot.
-Night Vision: How does a bow gives you night vision anyway? And it's the kind of enchantment that would be available only on helmets/hats
-Detect Life 300mt: Holy jeebus man, that is way too much. Also, this just like night vision is an enchantment for helmets, and the same question above applies here.
-Increase skills: Okay, 20 is way too much for a single piece of equipment, especially when it's already with those two above, plus you want to add 2 more skill modifiers in it, making it just atrociously overpowered.
Bow enchantment would be things like fire damage, or frost damage. Actually this applies most to arrows, but you get the point.
