ok, virus HERO, make a skin (or use an old one, but please make a new one), put it in a map and adjust settings, it has to be a hero, change the name (and proper name) and give it some new abilitys (all must have some triggering)
So it needs to be skinned from a hero, or skinned from a unit as long as it ends up to be a hero... Reason being is that a glow effect may be more trouble than it needs to be... Just asking this now...
just add the hero glow, it can be on any unit and a tip: USE ALPHA ABUSE, some good examples is here:http://www.wc3campaigns.com/files.php?do=viewfile&file=1019&s= look at the asymble guardian, he is great, eh? he is made from the pitlord, major alpha with reskin and particles.
