i need a spell that makes one units buffs effect other units

i need a spell that makes one units buffs effect other units

I need a spell that, if cast on a unit with buffs/debuffs (both), makes all units in X area near it receive the same buffs

only way is to make another spell that has the same buff effect and give this ability to a dummy unit. pick every unit withing XXX range of the targeted unit of ability being cast and do multiple actions: order dummy to cast the dummy spell on picked unit and remove dummy afterwards

you couldn't use jass to get what buff it has on it then cast the spell that uses that buff on all units within x yrds?

couldn't you do an if buff = (buff) then cast (spell) else if (other buff) and one for every buff?

im using vexorians caster system if this would help anyone out any
