Passive and skill idea. A mix of Ziggs, Kalista and GP

Hey guys, this is just a random passive, skill ultimate and that I had while trying to sleep. So here it goes :

Passive (Sticky bomb) - Think of it like a gooey bomb similar in smash

(Insert champion name here) auto attacks don't do damage. Instead, he puts a sticky bomb on targets that can explode at his will Each sticky bombs has a small detonation aoe and nearby ennemies take 50%/75%/100% dmg of the aoe. They can inflict critical hits like a basic auto attack. Each succesive detonation will add an extra 10/20/30 physical damage (level 1/6/11).

Sticky bombs last for 25 seconds and must be near (Insert champion name here) to remain active. Otherwise they just deactivate and deal no dmg

E skill - Detonation - Like kalista, twitch

(Insert champion name here) detonate 1/1/1/2/2 sticky bombs on every nearby enemies affected by a sticky bomb.

Cooldown : 2/1,75/1,50/1,25/1,00 Mana cost : 0

R Ultimate - Bomb supply - a mix of Ziggs and Gangplank ult

(Insert champion name here) calls down for help and a huge crate containing sticky bombs will drop on the target location after a short delay. Once the crate crashed down on the ground, a load of sticky bomb will surround the floor. Enemies who walk on it will have a stack of sticky bomb on it.

Crash damage : 200/300/400 (+physical dmg %) Aoe of sticky bombs on the ground 300/350/400

Q and W skills could be a slow, a dash, shield or something that provides utilities. Haven't thought of it yet.

Let me know what you think!
