Amalie, the Last Lullaby
Passive- Beauty Sleep
If she doesn't move, use abilities, or attack, for 2/1.5/1 seconds, Amalie begins rapidly regenerating health and mana until she does one of those things. (She has a 'sleeping' animation which she uses while doing this.)
Q- Good Night
Cooldown: 15/14/13/12/11 seconds
Damage: 80/110/140/170/200 (+60% AP)
Amalie fires a skillshot that damages the first enemy hit. Every third cast, if the enemy is a champion, for 2/2.5/3/3.5/4 seconds, they lose vision from minions, towers, and wards, and their vision radius is reduced by 30%.
W- Sleep Tight
Cooldown: 16/15/14/13/12 seconds
Amalie fires a skillshot that puts the first champion or minion it hits to sleep, stunning it for 1/1.5/2/2.5/3 seconds. If the target takes damage while they're asleep, the duration of this stun is reduced by .25/.5/.75/1/1.25 seconds.
(The number of attacks it takes to wake the target up decreases as the game goes on, since each attack hurts more.)
E-Don't Let The Bedbugs Bite
Cooldown: 13/12/11/10/9/8 seconds
Damage Per Second: 40/55/70/85/100 (+15% AP)
Amalie deals damage over three seconds in a moderate area. Don't Let The Bedbugs Bite deals 40% more damage to targets who are immobilized and 20% more damage to targets who are slowed.
R- I Dreamed A Dream
Amalie creates a large zone on the ground (GP ult-style) for three seconds that increases the duration of allied CC by 10/20/30%. At the end of the time limit, Amalie creates a Nightmare at target location. The Nightmare has 300/375/450 (+10% AP) health for each hard CC effect that landed within the circle, and 50% of that for each time a champion was slowed. The Nightmare moves rapidly (400/425/450 MS) and its attacks deal 70/90/110 (+20% AP).
Anyway, just an idea.
