Ok, I see your issue. When the target unit takes damage, although you can check what type of damage that was, be it spell, physical, or from code, you can't actually detect what spell that damage came from. Poison arrows are a pseudo magic/physical attack, meaning that they can be evaded like regular physical attacks.
If you have instant projectiles, here's what you can do
On Poison Arrow Cast, add a buff to the attacker
On damage, if attacker has buff and damage was from magic (not actually sure if it's magic or physical tbh, you'll have to check), add the extra damage
On timer of 0, remove the buff from the attacker (you can't do an attack faster than like .01)
If the projectiles aren't instant, your only good option is to use a custom projectile system and then specifically deal the damage to the unit when the projectile collides.
This is an example of how you'd do it if it was a buff on the unit and the damage was physical
JASS:
struct PoisonArrows extends array
private static constant integer POISON_ARROW_BUFF_ID = 'buff'
private static method onDamage takes nothing returns nothing
if (GetUnitAbilityLevel(source, POISON_ARROW_BUFF_ID) > 0 and archetype == ArcheType.PHYSICAL) then
set damage = damage + GetHeroStr(source, true)
endif
endmethod
implement DDS
endstruct
JASS:
struct PoisonArrows extends array
private static constant integer POISON_ARROW_BUFF_ID = 'buff'
private static constant real MULTIPLIER = .5
private static method onDamage takes nothing returns nothing
if (GetUnitAbilityLevel(source, POISON_ARROW_BUFF_ID) > 0 and archetype == ArcheType.PHYSICAL) then
set damage = damage + GetHeroStr(source, true)*GetUnitAbilityLevel(source, POISON_ARROW_BUFF_ID)*MULTIPLIER
endif
endmethod
implement DDS
endstruct
So level 1 = half hero str
Level 2 = full hero str
Level 3 = 1.5*hero str
etc
w/e you want
Hopefully I have answered your question
Will there ever be a system that can index attacks? No, it's impossible to index projectiles.
