User blog comment:LivesByProxy/LBP's Design Challenge - The Smuggler's Passage/@comment-26378838-20160222183954

Call me crazy, but this would be a great ability for a Mind Flayer type of champion, one that plays mind tricks on its enemies. Here are a few suggestions for such a character:

Passive: 

1) Ceremorphism: Basically Trickster's Glass active in a passive when the enemy team doesn't have vision on the champion;

or

2) Call to Insanity: Procs a Charm if enough damage is dealt to the target within X seconds.

Basic abilities:

1) Abduction: Smuggler's Passage;

2) All-Seeing Eye: Deals AoE damage in a cone and grants true sight for X seconds. If it kills an enemy unit, it creates a ward that flies away for Y seconds;

3) Mental Mirror: For the next 2 seconds, the champion and a target enemy champion will share vision, damage suffered and crowd control effects;

or

4) Walk into the Unknown: Ground-targeted AoE that deals damage to enemy units and makes anyone that walks on it warp to a random location within X units. It also grants vision of enemy units that walk into it;

Ultimate:

1) Mind Flay: Creates tethers in a cone that may hit enemy champions and deal damage every 0.5 seconds for X seconds and causes Dementia for Y seconds if completed. Dementia makes its victims act randomly (by either walking erratically, acting like it's taunted or even using basic abilities without the player's input).
