How to remake spells or feat icon and description which is already existed?

I customize the effect of epic spell mummy dust,so i want it more like my own thing.But i don’t know how to changge the icon or descrition of spells.

I realize that i can edit dialog.tlk to change name and discription.But how can i change the icon?I don’t need customized icons,just original will be ok.
I simply edit spells.2da,but it doesn’t work.

Try looking at how @TheAmethystDragon went about it with their Colorized: Spell Icons: Generation 2. That should help you to figure it out.


Thx,I know what’s going on. :joy:
The epic spells are considered as feats not spells,i should modify the feat.2da.
