We should make Amumu the corruption spreading mummy that he is in his lore.

The PBE changes are a great first start but they barely do anything besides letting him apply his passive to multiple targets. His current passive is actually a lot stronger than his new one on enemies who don't build MR. The multiple target curse makes it a net buff, but just look at his kit, there's still a lot of work to do to get him in line with newer champions. His kit's age shows, hard.

Passive: Increases damage Q: Stun + damage. Huge cooldown makes it engage only. W: Damage. E: Damage. R: Stun (technically entangle) + damage.

Amumu is just one step above Dr. Mundo, a champion that builds full tank and gets nothing but damage from abilities. You engage, ult, and that's about all you do in a fight. I like the idea of his abilities having very light debuffs but in plentiful supply and affecting the entire enemy team. He would actually fit his lore if he had a kit like that.

Ideas

Q: Keep the stun + pull, reduce the damage. New: applies woe to the target and enemies near the target in a very small radius. Woe reduces the damage dealt by the target by X% for 3 seconds. This change makes his Q an engage and gives him a small window of time for his team to catch up without exploding when focused thanks to the damage reduction. It heavily punishes enemies grouping together but the simple counterplay is to not stand right next to each other. W: Keep the damage or possibly reduce it very slightly. New: now applies decay to targets. Decay slows enemies by an extremely light amount. I'm just spitballing here, but I think 3/5/7/9/11% would be great. It's not oppressive at all but it allows Amumu to utilize stoneborn pact, giving him more utility without changing his kit a ton. E: Honestly this is a pretty lame part of Amumu mostly used for proxxy farming waves and clearing camps. In fights it has pitiful damage and bleeds you dry of mana. It would be nice if it was completely changed, but I have an idea to update it without completely scrapping it. New: Tantrum applies rotting to all targets hit. Rotting completely prevents healing from all sources for 1.5/2/2.5/3/3.5 seconds. It's another light debuff that adds up nicely to his debuffing kit. R: Keep it as is, possibly reducing damage very slightly. New: Passive: Mold: Enemies who basic attack Amumu have their attack speed reduced by 15/25/40% for 2 seconds. Attacking Amumu refreshes this debuff. This discourages ADCs from attacking Amumu while he has other, squishier teammates to target. It's not huge, but it can be useful in a meta where champions can ignore ~65% AR with last whisper and black cleaver

Overall, it's 4 very small additional debuffs that make Amumu feel like a cursed mummy rather than an ult-bot. His overall damage can be reduced slightly to allow for the new debuffs to fit into his power budget, but he would need slightly enhanced damage to monsters as compensation because the debuffs are useless against them.
