Random Ability idea List

Hey league boards! Im a huge fan of league and often think of ability's i would like to see in the game. These abilities are by no means balanced but i like to believe that they are pretty unique. I hope you guys enjoy reading these, and make sure to let me know which ones you like or even comment some of your own ideas below.

Passive: Walking creates a path of ice that slows enemies that walk on it. This disappears after a couple of seconds have passed.

Passive: After dying, you leave behind an unbreakable but visible ward. This ward lasts until you respawn, but you can press any button (QWER) to make it explode and stun enemies in an aoe that last 1 second but the ward disappears.

Ultimate: (Lets say you are a champion that is a ghost in armor) You leave your armor body and gain 50% attack speed and movement speed and become invincible. However, you are tethered to your armor so you cant go too far from it and enemies can still freely attack your armor body to kill you. The ult also has a time limit that, when it runs out, pulls you back to your armor body.

Ultimate: You gain a special shield that reflects the next 5 Skill shots back to their original cast location.

Regular ability: You create a tether from yourself to an ally that drains your own mana by 50 every second, but restores your allies mana by the same amount.

Ultimate: You shoot a point and click projectile towards an enemy that kills them immediately. However, you can only gain one charge every time you upgrade your ult. (essentially you only get 3 charges of these total)

Ultimate: You become immobile and cannot attack during this time. If an enemy attacks you during this state, they will receive all the damage back to themselves while you take none (When it ends of course). However, if nobody attacks you during this time, you will deal damage to yourself.

Ultimate: You take over the body of one enemy and are able to use their skills and items to attack their friend. But your own body is vulnerable while you take over theirs. This also has a limited duration.

This is all i have for now, but i will add more when i think of some. I would love to hear some of yours!

(Remember: They don't really need to be balanced, as long as they are unique ^.^)
