Small rework of Nautilus' W

W: Titan's Wrath

Cost: 60 / 65 / 70 / 75 / 80 Mana Cooldown: 16 / 15.5 / 15 / 14.5 / 14

Active: Nautilus cloaks himself in abyssal energies, shielding himself for up to 6 seconds.

Shield Strength: 70 / 85 / 90 / 105 / 120 (+7 / 9 / 11 / 13 / 15% Maximum Health)

While the shield holds, Nautilus' basic attacks apply Abyssal Curse to his target and nearby enemies, dealing them Magic Damage per second over 2 seconds. Subsequent applications will refresh Abyssal Curse.

Enemies with Abyssal Curse that deal damage to Nautilus while the shield holds receive a tick of Abyssal Curse's damage instantly.

Magic Damage per Tick: 10 / 15 / 20 / 25 / 30 (+15% AP) (+1.5% of Target's Maximum Health)

Numbers probably aren't perfect, but the concept is there.

Basically, the lower cooldown and mana cost, plus the return damage, are intended to help Naut get back into the jungle. Plus trying to re-tune it to compensate for Health being lowered across items, while reducing the annoyance of a 10-second gigantic shield.

I guess maybe his E damage might have to be nerfed a bit if W provides more damage/uptime, maybe. It did just get that mana cost increase plus his base mana regen going down, so I don't know.
