Polaris (the gravity mage)

Creating my own champions is something I don't do very often. I usually only do it whenever I am bored and sometimes it is fun to just think of new ideas and abilities that would be fun to see in league some day. So, I do not have my own lore written for this because I am not the greatest at that but here is my idea I came up with for a support mage named Polaris.

      (Passive)
      Earth Bound - Polaris is gravitationally attuned to the ground and if he is hit with a knock-up, push, or pull he resists it and stays in place. He can resist one effect before this passive goes on cool down.

      Gravity Mine -  Polaris conjures a bubble of gravitational magic at a target location. After a short delay, the bubble becomes hidden to enemies and is ready to be activated. Once an enemy steps on the trap the bubble explodes, dealing magic damage and suspending the target in mid air for 1.5 seconds.

      Fluctuation - Polaris generates a gravitational field around himself for 3 seconds, slowing enemies inside the field for a set % and the slow increases based off of Polaris's AP.

      Rupture - Polaris sends forth a pulse of magical energy through the ground. This energy passes underneath any walls or enemies until it reaches its target location where it bursts from the ground, dealing magic damage and slowing the target by 20% for 2 seconds.

      (Ultimate)
      Gravity Well - Polaris conjures a ball of unstable magic at a target location that releases a burst of gravitational energy every second for 5 seconds. Each burst of energy deals magic damage and slows any enemies in the field by 5% for 2 seconds. Each time an enemy is hit by a burst of energy, their slow stacks up to a maximum of a 25% slow after the final burst. After the 5th explosion, any enemy hit by all 5 bursts is stunned for 2 seconds.


      So that was my design for Polaris the gravity mage. I hope that anyone who reads this enjoys it and if you want to give any feedback about changes you think would make it better then please do so. I would be more than happy to help make this as balanced as possible and to just make it better overall. This will never be a real champion in the game but I still want it to be the best it can be for myself. Thanks for reading!
