L2J Server

Hi all ^^
I post this in l2jserver but nobody help me XD
I have a interlude server and I se that Interlude don't have PhoenixBless effecto in it's java...
I try to add the phoenixbless effect using a T1 server like as a model and I add a EffectPhoenixBless in skills/effect folder, add the PhoenixBlessing in the L2PlayableInstance, add the PhoenixBless in the L2Characters and in L2PCinstance but it don't work...
I only need to make this allow to revive a dead character, but I try and it don't work...
Can please explain me about this? or make a patch to add this in a interlude server please?
I don't are a great java programer but I make some custom modifications in the java and all work great but never modifi a effect of a skill exept in the datapack...
Please, help me with this

Why you don't use a updated l2j gracia server ?

We are not supporting very old chronicles.

I don't like gracia client, gracia core are great, I se this and I use it in some test of skills that I change delay or duration to the gracia datapack, but the gracia client are gratly hard and don't like to all people, the interlude client are more soft and a basic pc can run great it...
Simply, I love interlude client XD
