[champion idea] theonia the elemental swordsman

Theonia would be a swordsman using the 4 elements to fight

[Passive] elementary combination each spell Theonia use changes its effect according to its elementary stream and uses the elementary stream (except for the ultimate)

[Q] fire blade default: on her next basic attack Theonia deals damage in a cone in front of her elementary stream earth: the blow stuns the enemy but do not inflict area damage elementary stream air: the damage and range of the cone are increased elementary stream water: Theonia propels herself forward inflicting great damage on the entire length

Theonia gets elementary stream fire for 2 sec

[W] ground assault default: Theonia propels herself forward while pushing the enemies she touches to the side and inflicting damage Elementary stream fire: Theonia no longer knocks enemies but leaves a lava trail behind her elementary stream air: Theonia creates a wall behind her elementary stream water: the range is quadrupled and all the enemies are thrown into the air instead of being pushed

Theonia gets elementary stream earth for 2 sec

[E] aerial assault default: Theonia teleports to the target dealing damage Elementary stream fire: Theonia deals damage around the target as well elementary stream earth: Theonia stuns the enemy but does less damage elementary stream water: the damage is greatly amplified

Theonia gets elementary stream air for 2 sec

[R] aquatic charge Theonia gains movement speed over time after 2 s Theonia gets elementary stream water and can reactivate the ultimate if she reactivate it she will propel herself forward creating a small tsunami pushing enemies and inflicting damages (though she will lose the elementary stream water)

a rather complex champion (it may be a little too complex) but with many possibilities and combos I think it would be fun to play but also very hard

give me your opinion
