While trying to figure out the math for Hungering Arrow, we discovered that we don't know how the Devouring Arrow rune works:

Hungering Arrow: Fire a magically imbued arrow that seeks out targets for 115% weapon damage and has a 35% chance to pierce through targets.

Devouring Arrow: Each consecutive pierce increases the damage of the arrow by 70%.

Does this mean that each hit gets another 70% weapon damage added (so a second hit would be 115 + 70 = 185%)? Or that the total damage is increased by 70% (so a second hit would be 115% * 1.70 = 195%)? Or something else? This doesn't make a big difference on the first hit but the cumulative effect could be large.

I tested it and it is most likely that it is the 185% so it just adds 70% (115+70)

to the data:

normal hits without pierce made up 50 dmg that are 115%. so 100% wpn dmg was about 43.47 i'll take 44. 70% from 44 are 30.8. so one pierce would make 80 dmg, 2 would make about 110 dmg and 3 would make about 140 dmg

I shurely collected more data. one Pierce made about 80 dmg 2 pierces made about 110-120 dmg and 3 pierces made about 140-155 dmg

As you see it is the 185% weapon dmg.

All data was made with a 16.5 dps 2 handed crossbow 14-16 dmg without any other gear on a mallet lord in act4 hell with my DH lvl 60. Additionaly i had no dmg buff passives active (had hot pursuit, brooding and tactical advantage)

  • By my math, if it worked the other way, 2 pierces should be 145 damage and 3 pierces should be 245 damage. These numbers are sufficiently different from what you saw that it looks like you're right!

I would tend to think that it increases your total damage because of the wording.
"Devouring Arrow: Each consecutive pierce increases the damage of the arrow by 70%." Total damage of the arrow is 115% weapon damage and then your second iteration the 195.5% damage would be correct.


From the wording, I'd disagree with Chris Porter. It says it increases the damage of the arrow, not the damage done. The damage of the arrow is 115% weapon damage, +70% = 185%.

That's taking the wording very literally though, it'd be interesting if you could accurately compile some data on it. Due to the range of damage of a "hit" you'd have to take quite a few samples compile the data and compile a mean average of the second hits damage. Too time consuming for a monk like me :P

But yah, I'd bet you dollars to doughnuts it's only 185% damage...
