hey there, I’m trying to build a hail of arrows build and I have a question about damage scalling on this skill.
I’ve got the node that makes the skill be converted from physical to cold damage, and it says:
“Hail of Arrows’ base physical damage and added bow damage is converted to cold. Consequently this damage scales with increases to cold damage, but not increases to physical damage”
the scaling tags are:
“Cold, bow attack, damage over time, dexterity”
actually I have two questions, first one is: how the bow attack is applied to the damage? if I put a normal bow without any stats, just the base stats of a recurve bow for example (1.05 base atk rate, +33 physical damage), why my damage goes up? if the bow is only giving me physical damage it shouldn’t be increasing my dps, right? it’s probable because of the “bow attack damage”, if so, it doesn’t make any sense to say that any increased physical damage would not scale with the hail of arrows 
and the second one: why the Hail of arrows damage goes up (a little, but goes) when I equip an idol that explicitly increases physical damage for X%? why is this scaling when it shouldn’t? I tested two of the same bow, one without affixes and other with T2 increased physical damage, why the one with the affix increased the DPS of my hail of arrows?
thanks in advance!
