Champion Fan Concept
So since there aren't really any Earth/Rock commanding champs in league (Malph being the only one and he is kinda made of it, not really commanding it) I'm thinking a Rock based melee Fighter/Tank. Based around martial arts, body's natural motion and of course the Earth. I don't have a name or actual character model in mind for this but I've thought a bit on the skills/passive and stuff.
Passive- Gaia's Child- Gaia lends you her aid when reaching below 30% hp. Encompasses you in earth for 1 second while becoming immune, then burst out cast in stone, removing all imparing effects and making you immune to movement debuffs and increasing damage dealt for the next (3?) seconds.
Q- Erupting Spire- Focus your power through the ground, stomping down to force a spike to jut out of the targeted wall, dealing magic damage and displacing the target(s) affected away from the spike. Point and Click Area of effect spell, no target required.
W- Tai Chi Ch'uan/Tui Shou- Passive. Internalize your power every (3?) attacks, granting the next strike to do slightly increased damage and marking that target if they are a champion. Active- Harden your fist to stone and use the force and movements of the last Champion marked, you do increased damage and suffer less from impairing movement from that target for (x) seconds.
E- Serpent Strike- Lashes out with 3 fingers, forming a rock serpent to attack pressure points in the neck, stunning the foe for (x) second(s). Ranged/Skillshot/Single target
R Seismic Vault- Jumps to the target location and smashes the earth around you causing an earthquake, massively slowing foes and making all airborn debris to form around as an Earthen shield, while the shield persist you will have increased physical defense ( and a shield). Physical Defense and Shield scaling off of your current Magic Defense.
The R physical defense scaling off of magic defense would be good for balance, since you won't have enough physical defense from just your R to live nor just being good against all physical damaging teams. Idk if I want Q/E to be switched or what not but yeah this is my idea for a new champion. Hope you enjoyed. Feel free to ask any questions or inquire upon improvements! :D [slayer-jinx-wink]
