How to add special effect to specific weapon

[103Sakamoto]

I'm using a two hand weapon mod,The Fume Ultra Greatsword from Dark Souls.
In Dark Souls,the normal attack animation of fume is familar to the two hand weapon power attack in skyrim.But unlike the effect in Dark Souls,when using the power attack,when I hit the air(because this is a very huge weapon,it's hitting ground actually),it's feels very weak,without screen shake and sparks.(I'm using TK hitstop mod so when hitting enemies,it looks acceptable)How can I add some effects to this specific weapon?Is xedit possibleï¼
