Arrow Mutation is a bow mod that converts any unused Secondary Ammo into Arrows, though does not affect their ammo capacity. The affected bow will only convert ammo while equipped, and will not convert any ammo type used by holstered secondary weapons until their own ammo is full.
Converted ammo is denoted by a 
symbol. The final amount of ammo restored is rounded to the nearest integer.

Got it after 20min in Tycho Lua.
Easiest way to get this is through Apollodorus (Mercury). I got mine after 20 mins. The enemies are very low level so you can just breeze through it
If any one has a spare they don't want, hit me up Kage Deamon xb1
I have got this mod during Excavation mission on Earth, Cambria Node. Was quite surprised.
ammo mutations get excavated alot, its not only arrow mutation
so if anyone needs one, go to earth :)
20' Apollodorus. Haven't seen one of those in a while.
Personally, when I use this, I only use an unranked version. It is already gives plenty of arrows per pickup. Looking at it, if each enemy drops 1 random ammo box per death, then assuming you one shot each enemy, it will cover your cost, if not more.
Better yet, just don't use it at all. I never run out of arrows as it is without ammo mutation for it.
How far is it worth levelling this then? 'cause that'll get you a lot of arrows...
... to the knee.
... if you actually do rank it. Use at zero, it's more than enough.
Just found this in Lilith Europa, 10 minute reward.
not eaven on 20min
just picked it up on Apollodorus 20 min in
Same, but 5 minutes later.
I pick up sniper ammo for my bow
Got it after the 25 minute mark on mercury's survival as a drop.
perfect for my new paris and soon my new paris prime AHAHAHAHAHAHAHAHAAHAHAHAHAHAHA(any corpus reading this I will work for rare items and blueprintsP.S. I mean work as In slaughter your enemies not be a cashier)
meow
Paris prime is even more evil against Grineer :D
If you wanna level up a Paris prime, just bring it to earth's survival mission. Even an unmodded Paris prime can one shot kill most Grineer enemies there. Advice: give it explosive arrow and multishot mod... Properly modded, a paris prime can be one of the best primaries you can get your hands on ;)
Explosive arrow mod is called thunderbolt
mission on mimas at 40 or 45 mininits. dont remember
it's definetly not 45 min, so it's definetly 40 minutes.
I got it on Apollodorus, at 20 min :p
Cambria-Earth-20 mins
I was very surprised to get this, I was intially farming for fusion cores, then this thing pops out of nowhere. It's also now my first mutation :D
Lucky you, I got all Muations mods in big numbers, but sadly Arrow is still missing. At least I got Shotgun 6 times and Sniper 8 times.
I was given all of them as an event reward
Bows draw from The sniper ammo pool and there's a sniper ammo mutation so what's the point of this?
You can't equip sniper mutation on a bow :P
This ^.
Got it now on E Gate minute 20.
apollodorus 20 min
35minutes, E gate. those triple digit corpus LOL, 2nd time i died on my nyx ever
Mabye a bug or bad memory, I know I have this mod, I think I got it at the 5 min mark at Appollodourus.
30 minutes on Earth - Cambria, got Pistol at 20
