FX scale for existing skill

Hi. I’m trying to increase some centered on char. skill’s radius, like Necro’s “Soul Siphon”. And while I found how to change actual numbers, I can’t get around PSEditor. Is there a way to find what textures are used in particular skill? I mean, if I want to just scale fx’ radius ( to make SS like Olexa’s FF, 16m, for example here) do I need to recreate whole fx? Like check all textures in PSEditor till I find needed, set its settings etc.
