Is there a code for adding more arrows? Special arrows aswell.

you could just use money cheat and buy them. the elven ones work pretty well.

You can enchant arrows too I think.... not sure.... anyone know?? But I am pretty sure you can Enchant the Arrow, Enchant the Bow, Poison the Bow, and use glass/daedric arrows and daedric bow (there IS a daedric bow right??), for the most powerful sneak shot available...

Sound right??

Cadaver

I already have the deadric bow with an enchantment(lightning) but I never use it anyway. I use my deadric sword with the same enchantment and overly powerful full set of deadric armor. Its all good.

the only possible flaw in your theory is that there may be a legendary bow in the game, but I'm level 47 and have yet to find it. If there is no legendary bow in the game, your theory checks out with me!

The general code to add items is:

player.additem [itemID] #

Of course, you have to find the item ID in the Construction Set....

Edited to add:

Here are a few codes-

0004BF01 Arrow of Scorching
0004BF02 Arrow of Cold
0004BF03 Arrow of Shocking

0004BF0D Arrow of the Inferno
0004BF0E Arrow of Winter
0004BF0F Arrow of Storms

The rest can be found in the CS under Items-> Ammo
