Champion Idea: Rex the Vengful

Hey guys this is my first champion idea so I hope you like it. I have not included any base stats or ability damage because I want to just focus on the design of the abilities and cohesiveness of the kit itself. Any and all feedback is appreciated.

Background: Rex grew up in Piltover and just like many other Piltover children, she loved to tinker with machines. Rex has always idolized Vi for her determination and power, which is why there was no question that Rex would join the Piltover Police Force when she was old enough. Her first week on the job Rex is sent to investigate a known hiding place of Jinx. As Rex enters the abandoned building she cant help but feel like something is wrong. Just then she turns a corner to see a large timer hit 00:00. One month later Rex awoke in the hospital and found that much of her body was replaced by mechanical parts. Her life changed forever Rex quit the force and now seeks revenge on the psychotic menace who destroyed her life.

Visuals: Rex is a female of normal height and build much like Vi however she has long green hair that comes down and covers the right side of her face. The Left half of her skull is now mechanical with her left Eye glowing green. Her left arm, left knee, right hand, and both feet are mechanical as well. Rex wears black pants and a black vest with metal and green accents. All of her abilities have a green glow and her auto attack is a green energy ball fired from her right hand. She is a tough champion but never forgets her need for revenge that fuels her rage.

Passive: Overcharge Rex's abilities fuel her rage. After using an ability, Rex's next auto attack deals bonus magic damage equal to 100% of her Ability Power.

Q: Power Beam Rex fires a laser in the target direction dealing magic damage to all enemies hit. (Instant cast and instant damage. Much like Xeraths's Q however it is half the width and 3/4's max length.)

If Rex is mounted the beam becomes a cone of the same length. Final cone width approximately 300 units.

If Rex is mounted on Energy Wall (W) or she fires Power Beam (Q) through Energy Wall (W), the damage is increased.

W: Energy Wall Rex Places a wall of pure energy on the field (can be passed through). Dimensions W x L x H, 80 x 500 x 250. Placement mechanics are similar to that of Karthus's W. If an enemy passes through Energy Wall (W) they are slowed.

E: Hextech Boosters When activated Rex dashes in the target direction 300 units. Can pass through small terrain.

If Rex is dashing through Energy Wall (W) the range of the dash is increased to 300 units away from Energy Wall (W). Also Rex gains a short speed boost after exiting the dash.

If mounted the range is increased to 1300 however Rex can only jump in a cone away from the terrain she is mounted on. Similar to Zac's E. When Rex lands she does damage to all enemies in a 200 unit radius.

If Rex is mounted on Energy Wall (W) the damage upon landing is increased.

R: Wall Mount Rex jumps on to the targeted terrain and clings to the wall. Rex can mount on any terrain including player created as well as Energy Wall (W). Rex can reactivate Wall Mount (R) once to jump to, and mount on, another piece of terrain that is facing Rex and within 500 units. Rex can only mount on terrain that is facing her and she can only jump off of terrain in a cone away from the terrain she is mounted on. (the only exception to this is Energy Wall (W) which she allows her to mount onto either side regardless of which side is facing her.

While mounted, Rex's attack speed is greatly increased.

Wall Mount (R) has a fairly low cooldown. (I was thinking 45s at max rank)

Explanation: So in my mind Rex is an AP assassin that specializes in maneuverability. She is very squishy however her superior dashes and jumps give her an advantage. The best players will take advantage of her passive to deal the most damage.

Thanks for reading I really hope you liked the idea. Any and all feedback is much appreciated.

Thanks! -GRC
