Terra, The Ground Breaker - New Champion Concept
Sorry I haven't fleshed this out, I don't have artistic abilities in the least so no pic or anything.
Primary Role: Mage
Secondary Role: Tank
Lane: Mid, but maybe top or support bot.
Passive: "Firma" Terra's abilities create stalagmites in their area of effect. Stalagmites reduce damage that Terra takes by 1/3/5% to 2/6/10% depending on how close to one she is standing. Stalagmites also slow enemies by 2/6/10% to 4/12/16% based on proximity as well. Stalagmites last 2 seconds before returning to the earth.
Q: "Aftershock" Terra causes the earth to shake in a straight line. This deals more damage to close enemies and less to those farther away. A stalagmite is formed at the end of the line, slowing enemies.
W: "Sinkhole" The ground gives way in a small circular area dealing damage to those inside. Three stalagmites form a triangle around the hole, slowing enemies. After the initial damage is dealt, the area becomes quicksand, dealing light continuous damage to all of those inside. Quicksand slowly drags enemies toward the center of the hole unless they are actively moving against it. Quicksand also deals increased damage if more than one enemy is in the hole.
E: "Commune with Nature" Passive: Terra can feel the presence of invisible wards, traps, or champions in the area around her. She cannot see them, but a small visual cue above her head notes that they are present (Green for wards, yellow for traps, red for champions - this overrides the normal mark for rengar's ult detection)
Active: Terra casts an AoE spell that has different effects depending on the terrain it is cast in. It is circular and the effect depends on the terrain in the center of the circle.
Ground: A volcanic eruption occurs that damages enemies and lowers their damage output for 2 seconds. Two stalagmites are created at the location.
Water: A geyser erupts at the location that damages and knocks up enemies. Ripples extend from the geyser that increase the movement speed of allies running away from it. Two stalagmites are created at the location
Brush (on land or in river): A raised hill is formed for 3 seconds. Enemies on the hill are no longer considered "in brush" and are therefore revealed. Enemies hit directly are stunned for a short duration. Allies who stand on the hill gain increased vision radius (similar to Quinn's W) and increased movement speed when running down it.
R: "Quake" An earthquake occurs in a large radius around Terra. A stalagmite erupts at Terra's location. Enemies within the area are slowed for 3 seconds. Enemies are also damaged per second. After 3 seconds, enemy champions within the radius are dealt a larger sum of damage and stalagmites erupt at their location.
Terra is a mage that manipulates the playing field to her advantage. Her kit is widely varied and changes depending on her surroundings. Her Q and W have low cooldowns and can be used to poke effectively, while her E and R are more powerful but have longer cooldowns. Terra specializes in hitting numerous enemies at once and causing small doses of slows and damage that add up, rather than delivering her attacks in a single burst. Because of this, her ideal item set would include Rylai's and Liandry's to take advantage of the sheer number of hits her spells deliver, and she would be incredibly effective against tanks and groups of enemies in teamfights, while remaining weak to bursty assassins. When she needs to retreat, from a gank in lane for example, she can use her Q and W to set up a path of stalagmites that will slow her pursuers while increasing her defense.
