[Champion Rework] Nautilus, the Titan of the Depths
Base Stat Changes Health: 550 + (80) Movement Speed: 300
P: Depth Titan Passively, Nautilus is immune to knockbacks and knockups. Instead of displacing him, these effects will instead slow him for 80/75/70%, equal to the duration of the knockup. Additionally, Nautilus gains 40/45/50% of MS from items and runes. EX: If Nautilus buys Boots of Speed, at level 1, he will only gain 10 bonus MS.
Passively, Nautilus's abilities charge his auto-attacks. After casting an ability, Nautilus's next auto-attack will deal 4 - 55 + (0.35 AP) magic damage, and root the target unit for 0.5 - 1.5 seconds. If they target unit has been rooted by this ability in the last 10 - 6 seconds, the charged auto-attack will not root them, but will still apply the bonus damage.

Actively, Nautilus hurls his anchor. If he strikes an enemy unit, the target takes 80/120/160/200/240 + (0.75 AP) magic damage, and Nautilus drags himself and the target unit together, briefly stunning the target. If Nautilus strikes a wall or player created terrain, Nautilus dashes to the struck location, and the CD of this ability is halved.

Passively, Nautilus shields himself for 35/45/55/65/75 + (5/7/9/10/11% max health). This shield is restored through Depth Titan's empowered auto-attacks. Empowered auto-attacks against minions and small monsters restore 5 - 10% of the shield, while empowered auto-attacks against champions and large or epic monsters restore 10 - 20% of the shield. After the shield is broken, it cannot be restored until 12/10/8/6/4 seconds have passed.
Actively, Nautilus swings his anchor in a cone in front of him, dealing 65/85/105/125/145 + (2/2/3/3/4% enemies max health + 1% per 100 AP) + (1.00 total AD). Enemy minions and small monsters are pulled closer to Nautilus.
E: Depth Charge CD: 20/18/16/14/12 Cost: 60/65/70/75/80
Actively, Nautilus plants a Depth Charge, at target location. The Depth Charge preps for 0.75 seconds, then becomes active. If an enemy unit steps on a Depth Charge, it will detonate, knocking up all enemy units within 200 units, and dealing 70/100/130/200/230 + (0.75 AP).
R: Titan's Wrath CD: 140/120/100
Actively, Nautilus plants his anchor in the ground behind him, and becomes ghosted and 25/50/75% tenacity for the next 6/10/14 seconds. During this time Nautilus gains 150/250/350 + (10 per 100 AP) movement speed, but cannot cast basic abilities or auto-attack. While this ability is active, Nautilus can reactive this ability to grab an enemy champion, dealing 200/325/450 + (0.80 AP). Once Nautilus grabs an enemy champion, Nautilus and the targeted enemy champion are untargetable and suppressed, as Nautilus travels back to where he placed his anchor. Nautilus retracts to his anchor at a speed of 1500. Enemy champions struck by Nautilus retracting are knocked back, and take 100/163/225 + (0.40 AP) magic damage.
