The Corrupted Dragon

Pentiax

Surviving Pentiax's waves of fire and burning hail isn't easy – you'll want to find Invokers that can purge Burn debuffs, or with skills that cast Immunity to block the debuffs in the first place. And the quicker your heroes are, the easier they'll be able dodge his attacks or falling Darkstones.

Best picks: Invokers · Titans

Do

Make sure every Invoker has a Titan bound to them.
Bring Invokers that generate Titan Mana quickly – more Titans, more damage.
Time your Titans: a badly-timed Titan is a wasted Titan.
Bring heals and a way to avoid those Burn debuffs.
Stay on your toes: positioning and timing is key!

Don't

Pursue Pentiax once he flies away. You need to wait until he returns to attack him.
Leave your Titans at home.
Stand still.
Forget about Pentiax's Corruptions and Burns.

What it does

Takes 50% more damage from Titans and 50% less from everything else. Bind a Titan to every Invoker.

Hail of Voidfire: Falling rocks add a Burn and Mindfog, leaving fire pools for 12s.
Breath of Soulburn: A 5s sweeping breath that extends every Burn by 5s each tick. Bring Burn removal or Immunity.
Melody of Darkstone: Nightmare on everyone for 10s while stones fall and stun for 1s.
Roar of the Eternal: A big breath that summons 5 Fire Elementals.

Full boss briefing

As a former Titan, Pentiax takes much more damage from other Titans, but much less from Invokers. Bring high-damage Titans and Invokers that help generate Titan Mana quickly to maximize your chances.
