[Rework suggestion] Malphite
Simple but dynamic ideas.
Passive - Natural force: If Malphite uses two abilities in the same location (with the exception of W), it will create an area that will cause slowness to enemies. If one of the abilities has been used with Volcanic Strikes, instead of causing slowness, the area deals damage over time.
Q - Accumulate and destroy: Malphite begins to gather earth while moving, when activating the skill again, Malphite throws a ball of Earth in a straight line. In the first second of loading, the ground ball only deals damage. After 2 seconds of loading, the ball doubles in size and causes slowness After 5 seconds of loading, the ball causes stun of 0.50 seconds. (this is big enough to hit two champions at same time) For every 2 more seconds after the 5 seconds, the sphere increases in size, the accumulation of size has the limit of 20 more times. (When activated, malphite is unable to use other abilities) (It does not lose speed of movement when it joins earth, but slows down the buildup slower and stuns / snares stop growth, since it can not move [and no, snares, stuns and other abilities do not interrupt accumulate and destroy])
W - Volcanic strikes: Malphite is temporarily covered by lava, attackers suffer magical damage by inflicting physical damage to malphite while this ability is active. Activating a skill or attacking with AA's twice consumes this ability (if he activates this ability and then Q, attackers will not suffer magical damage, since the skill has already been consumed). If Malphite uses a skill after activating Volcanic Strikes, enemies struck by skill become fragile (that Ornn mechanic). (attacking with self-attack with this active skill deals damage to the area without activating fragility).
E - Land Rover: Malphite advances briefly and punches the ground, causing damage in area. (Skill can not be used to cross walls)
R - Uncontrollable force: Malphite advances straight and tosses enemies into the air. If Volcanic Strikes is active, it will melt the wall temporarily, allowing allies or enemies to cross it. (It would be interesting, however, instead of just activating Volcanic Blows to make way, he having to use two skils on the wall, to weaken it and then to ultar) (The ult of the malphite does not have enough range to cross two walls at the same time)
