Kog'Maw Rework Idea
Kog'Maw has always been meant to be a glass cannon, but as the mobility and damage are on the rise, Kog'Maw has been constantly crushed by the many of the popular assassins. This rework attempts to fix some of his major problems to keep him relevant, especially after the recent Rageblade nerfs.
Passive: Bio-Arcane Barrage- Kog'Maw's basic attacks are enhanced, causing them to deal additional magic damage equal to 4/5/6 (+1 per 100 AP)% of his target's maximum health. Additionally, Kog'Maw permanently gains 1 range for killing a unit, up to a maximum of 100.
Q: Caustic Spittle- Kog'Maw fires a corrosive projectile that deals 60/100/140/180/220 (+60% AP) magic damage to the first enemy hit. Kog'Maw gains 40/50/60/70/80% attack speed and basic attack damage against the target hit for 4 seconds. Cooldown: 12/11/10/9/8 seconds
W: Icathian Surprise- Kog'Maw causes a chain reaction in his body, dealing 200/325/450/575/700 (+120% AP) true damage to himself and surrounding enemies. For 3 seconds after casting, Kog'Maw recovers from the detonation, becoming untargetable and gaining 30/35/40/45/50% increased movement speed. Icathian Surprise can kill Kog'Maw, and if it does it deals double damage and his death timer is cut in half. Cooldown: 60/55/50/45/40 seconds
E: Void Ooze- Kog'Maw spews a ball of ooze that deals 80/110/140/170/200 (+65% AP) magic damage to enemies hit, leaving behind a trail for 6 seconds that slows enemies inside by 20/25/30/35/40% as well as grounding them. Cooldown: 16/14/12/10/8 seconds
Ultimate: Living Artillery- Kog'Maw launches a ball of acid that deals 100/175/250 (+50% AP) magic damage to enemies around the location. Living Artillery deals double damage against enemies below 30% health. Additionally, upon death, Kog'Maw launches two Living Artillery blasts at every nearby enemy. Cooldown: 2/1.5/1 seconds
The point of this rework was to give Kog'Maw more tools to kite his opponents, as well as being able to fight back well in melee range with Icathian Surprise, whilst keeping his ability to damage enemies even after his own death. Reply with any changes you'd make!
