Thanks @Proleric , I found that effect but the one I am looking for is the actual Cone visual from the hand or preferably the mouth like dragon breath.
Afaik nobody succeeded to make these spell visuals into classic visual effects. I think the primary issue is that these visuals needs a starting point and direction to use which is something you cannot do with EffectVisualEffect.
You were thinking right with fake spell but indeed that cannot be cast instantaneously. But there is a way.
Make the object to cast real spell, with bCheat = TRUE and bInstant = TRUE, also before that store a local int on object ie. SetLocalInt(oCaster,"FAKESPELL",TRUE); and then check this variable in spellhook and cancel the spell being fired if this variable is true and delete the variable.
I think the issue with using these effects is that the animation is called "cast01." A while back I converted all of them into regular vfx by making copies of them, renaming them to "vfx_conecold" for example, and changing the animation name to "default." List them in visualeffects.2da as Type F, under Imp_Impact_Node, and Orient With Object 1, and you'll be able to use them as instant vfx that look just like the spell effect.

In general, spells.2da gives the name of the spell script, which you can open to discover the visual effect required.
