Think "Tremors"

I'm trying to come up with a cool/viable worm champion here so as far as damage/mana costs/spell synergy leave me feedback and I'd be happy to update the skillset.



Lore: I don't read this **** so I'm not going to write it either.


Passive: Shed Skin - Every 12 casts, Vixen gains XX% of his HP back and loses all debuffs.

Q - Splurge
Vixen blinks to target location leaving a trail of goo, slowing opponents that touch it. Vixen's next attack will knock-back champions 200 range.

W - Hellion Drill
Vixen burrows into the ground creating a permanent hole which stuns Champions for .4/.6/.8/1/1.2 seconds and deals N(scaling per level) damage. (Max 2 holes. Size (50) Think Heimer Turret size and mechanics.)

E -
Vixen shoots tentacles forward 400/475/550/625/700 range which latch onto champions or minons for 2 seconds and deal damage per second, allowing him to pull them backwards and keeping them within the tentacles max range for the duration of the spell.

R - Creep
Vixen moves underground at increased movespead, avoiding both unit and structure collision for 9/11/13 seconds. Vixen cannot auto attack or be auto attacked, but can only cast his abilities or be targeted by abilities. Each champion Vixen passes under is silenced for 1.5/2/2.5 seconds
