Champion Concept: Miasma: Master of Traps.

My brain had an Idea after watching Shaco, Teemo, Jinx, and Nidalee lock a Sion down for half a year, I had a cool thought, What about a champion with a Kit designed around traps, locking an enemy away, and rejoicing in their terror as they get stunned, feared, rooted.. and executed.

Passive: Sadistic Tendencies; Miasma gains (high%) attack speed against targets who are Stunned, Snared, Feared, Rooted, or Silenced.

Q: Sharktooth Ankle Trap; Miasma lays a Sharktooth Ankle Trap(Just think of a bear trap made out of a shark jaw) within (X) distance of himself, becoming invisible after 2 seconds. Enemy Champions(and epic monsters) who step on the trap are rooted for (x) seconds. Taking (X) Physical damage and bleeding for (X) damage over 2 seconds.

W: Tripwire Explosives; Miasma Passively drops explosives against nearby walls every (X) seconds. When Miasma casts Tripwire Explosives he tosses a wire between 2 explosives, after 2 seconds the 2 connected explosives become invisible. when an enemy champion passes over the wire the two explosives explode towards each other, meeting in the middle(each explosion is a separate projectile, each doing separate damage so getting hit by both would do double damage), enemy champions hit with the explosion take (X) Magic Damage, and are feared for (x) seconds.

E: Spike Pit; Miasma Channels for (X) seconds, creating a Spike Pit, Spike Pits Decay after 2 minutes. The Spike Pit becomes invisible after 8 seconds. Any enemy that steps into the Pit Trap have a brief chance to move away before they are rooted for (X) seconds and take %HP damage.

R: Sadistic Automatic Warden; S.A.W. can only be cast on enemy champions who are stunned, rooted, slowed, feared, silenced, charmed, asleep, or airborne. Miasma Places a S.A.W. Mask onto the enemy champion, lasting for 1 minute. If the enemy champion drops below 10% HP they are executed. Fearing all enemy and allied champions for 1 second.(Globally) (yes, this is straight up the mask from the SAW movies.)

There ya go, Happy Holidays.
