I want to play an argonian acrobat, but I am not sure what of the marksman weapons an acrobat in TES universe would use. What do you think?

I'd think darts or throwing knives. Bows could potentially get in the way, being bulkier than the other options and throwing stars have too many pointed edges for poking into you while performing acrobatics.

Your suggestion seems to make sense.

Now to find mods that make darts and throwing knives more damaging and readily avilable or craftable....

Yeah I always had trouble justifying using them because I hated to lose them, especially those Daedric Darts!

In case you didn't know:

But otherwise, I'd suggest posting in the mod subforum and ask about some good mods which improve thrown weapons.

throwing weapons make a ton of sense for an acrobat. if you can't find a good mod, the dwarven dart added in tribunal has much higher base damage than standard game darts and knives.
