Here I fixed the whole stealth issue.
So I am pretty opposed to having an item that costs 75g make an ivis champs ability 100% useless. So why not make an actual Item?
Green Florecent Bomb
Price: 3500g, Range: 750, Radius 500, Cooldown: 120 seconds.
Builds out of

100 AP 250 Health 250 Mana 10% CDR
Unique Passive: Each minion killed grants Green Florecent Bomb an additional 0.25 AP to a max of + 20 AP
Unique Active: Throw down a Florecent Bomb in a targetted area to reveal INVISIBLE and Camoflagued Units.
PS: AD item coming soon, mostly for tanks/Juggernauts.
