also how do enchanted bows work ??? do they enchant the arrow or something ??? what would happen if i had a spark arrow and used a bow of some quitness would the spark effect become void and not exist ???

An enchanted bow will apply its effect to the arrow when fired. If the arrow itself is enchanted, the arrow's effect will not be nullified, so you will get the effects of both the bow and the arrow if both are enchanted.

Then if you want to have random fun, try seeing from how far away you can hit a hay target with your bow. It's fun, and it also helps your accuracy.

Here's some random fun with an unenchanted bow:

And some fun with a bow enchanted with Paralyze:

I'm rather fond of using my bow to set off tripwire traps, especially if there is an enemy to kill that way.

ok 2 questions

how did they kill that npc with out getting the guard to chase after them

and second how do you make a paralize bow ???

I'm guessing that the guard did not see the shooter. But I'm not sure.

Unless you're on the PC with mods y0ou cannot enchant a bow with paralyze. However, you can apply paralyze poisons to a bow.

Those were both my videos that I made.
1) No idea, but it could be due to the fact that, had the NPC seen me, she would have attacked me; she's a Mythic Dawn agent and my character had already completed Lake Arrius Caverns.
2) I don't remember, I know it wasn't poisons, it may have been enchanted arrows but I think it was an enchant on the bow, which means I have a mod that allows for that.
