How do I create a SpEffect that triggers on weapon attack and ash of war skill hit?

[languid dirge]

I'm trying to modify an effect to proc on both ranged hits and melee hits using weapons and their AoWs

I'm pretty new to modding as far as the complex stuff goes, but one place to maybe start following the trail would be to look at things like exploding arrows, and see if you can find where that explosion comes from, as that explosion has to be some kinda speffect to have the visuals and what not that it does. I'm struggling with a similar thing, but mayhaps yours will work easier since im working with torrent who has no attacks. Finding that ID/param that is the explosion of the arrows might just be what you'd need to tweak/work with to do what you're trying to do, as it's as close to an "on hit" effect I can think of.

If you want it to trigger when any hit from a weapon hits then you can just put the effect on the weapon itself under spEffectBehaviorId
If you want the effect to trigger on on some hits but not others then you will have to add these effects to the hitboxes you want them on

What if you wanted to trigger an speffect off of say an arrow? Like say I wanted to make a fancy speffect debuff or something else and hit mobs with it using bow and arrow, would you add to the speffectbehaviorid of the bow in question? or something else

Arrows are weapons so you'd add it to the weapon itself. However I've had trouble with this for certain effects but if that doesn't work then you can put the effects on the bullets themselves.

Nah, I'm actually creating a custom Fortune for ERR that functions the same way as the spellblade where Melee attacking gives you a stacking buff that boosts magic damage and stuff. The effect is already made but I'm trying to figure out how to make it work on Ranged weapons too

You add the accumulator on the bullet rather than the attack
