Ok, so I had an idea for a jungle/tank.

He looks like a cross between this:

And this:

So, just imagine a giant, shadowy Owlbear thing, and you're on the right track.

Also, if you can't tell, I like owls. Just putting that out there.

Passive: Delicious Misery:_ Asio has no mana, and all of its abilities are cast from HP. Asio's max HP increases by a small amount for every cannon minion, epic monster, large jungle creep, and champion it kills. It is granted more for killing champions than monsters. _ As Asio's max HP increases, his form changes into a larger, scarier form, with increased move speed, and defense stats.

Q: Phylactery of Shadows: Asio places down a dark orb. Within its area of effect, enemies are slowed, and take damage over time. As enemies take damage, the gem fills with their life force. Asio, or an ally may retrieve the orb for some quick HP.

Asio's Agents can pick up the orb as well, and are strengthened by doing so, temporarily gaining more attack.

W: Looming darkness: Asio throws out a shadow in a line, putting fear on enemies for 1 second (goes up to a max of, say, 1.25- 1.5).

E: Agents of Misery: Asio sacrifices a portion of his max HP, and summons an agent (a shadowy, rat/dog-like thing) that fights for him. They deal physical damage that scales with AP.

Agents will target whoever Asio attacks, but generally target the closest enemy unit. They place a higher priority on feared targets, and gain increased attack/movement speed against them.

R: Oubliette: Asio creates a zone of darkness, that blinds enemy champions, reducing their vision to a small radius around them (think Nocturne's ult). While inside of the zone, they take increased damage from Asio and his agents. Asio's abilities are also greatly strengthened inside of the zone, and it gains increased movement speed._
