Nautilus

Arena changes

• I: On-target cooldown changed to 5 seconds.
• W: Base damage changed to 40 to 100.
• W: Damage AP ratio changed to 55% AP.
• W: Base shield changed to 80 to 160.
• W: Shield health ratio changed to 9 to 13% of maximum health.²

• Reaper's Toll, Darksteel Talon, Cruelty, Reverberation, and Moonflair Spellblade are recommended for crowd-control champions; dash champions such as Nautilus can use Mirage Blade instead of Moonflair Spellblade.³
• With Reverberation, use W before the combo to add its on-hit damage alongside Nautilus's passive, Q, and R.⁴
• Center of the Universe works well on Nautilus because he can stick to targets and build defense and AP; it also works well with Omnivamp.⁵
• Nautilus and Poppy can wait for Alistar to use crowd control, then push him out of the fire and keep him there; the fire applies anti-shield and disrupts his Courage shield procs and passive heals.⁶

Nautilus's Q has two crowd-control effects: a stun and a drag.⁷

Nautilus can use Q and move back to cast Spellcraft while its cast time allows.⁸

• A full tank such as Nautilus can jump on a target, apply hard crowd control, and kill them with Void Immolation.⁹
• Nautilus can stand in front of an ally such as Jinx or Kog'Maw as a wall.¹⁰
• Nautilus is difficult to peel once he reaches a target.⁵

Ethereal Weapon with Moonflair Spellblade and Reaper's Toll can be a combination for champions with low-cooldown abilities, including Nautilus.¹¹

Tank Engine and Mercy can let Nautilus deal high damage with basic attacks.¹²

• Heartsteel is viable on tanks such as Nautilus.¹³
• Mercy is a damage augment for tanks with crowd control, including Nautilus.¹⁴¹⁵

Blitzcrank's R passive can stack on Nautilus and kill opponents during Guest of Honor selection.¹⁶

• Courage of the Colossus is very strong on Nautilus.¹⁷

Nautilus's Q can apply an excessive number of stuns per second because of a bug.¹⁸ Patch unknown

Nautilus can remain alive after the round ends while in Cannon Fodder; whether this is a bug is unclear.¹⁹
