Malus- The Forgotten Mercenary
Malus is a melee assassin who killed Yasuo's elder. He was hired as a mercenary for Noxus, feeling like his sword techniques was copied, he killed a certain Ionian Elder out of rage.
Passive- Santoryu Malus fights with two swords. For every second auto attack, he momentarily gains movement speed based on how much damage his previous auto attack did. In addition he also heals for a small percentage of the damage dealt.
Q- Blade Dance Malus summons a tornado to a certain location. The tornado follows the same corresponding path Malus is walking. Auto attacks and spells can be casted from the tornado.
W- Hidden Blade Passive- When out of combat, his next auto attack slows his target for a long duration. Active- Malus unsheathes his second sword. He gains double the attack speed for a certain duration, in that duration his third auto attack will always critically strike.
E- Silent Maneuvers Malus sheaths both his swords and for a short duration ,is able to walk through units. During the duration, he gains a huge burst of movement speed, when the duration ends he gains attack damage for an even shorter duration.
R- Merciful Malus shows his target mercy by killing them before they can feel pain, and they also have the chance to live longer. Malus sticks his sword in the ground, whoever has the lowest health points are rooted for a long duration. During the duration, Malus's next auto attack to the rooted target will execute them. If the target heals enough health points and survives, they gain movement speed and is no longer rooted.
Thoughts & Explanations Starting off with the Q ability: It is basically Zed's shadow except it can move and has longer range. Next with his W ability: This is to help Malus from getting kited. Also to add more burst damage. To explain, his auto attacks from his tornado and his own auto attacks aren't the same, meaning if played correctly can lead to the target getting hit twice with just one attack. Malus's passive adds to the burst damage along with the W ability to finish the target off. His passive can also be used to sustain him in lane, his Q ability can also be a farm tool as well.
Malus is more zone based, he can assassinate a target from far away, but he can also 1v1 the enemy top laner very well. Just to clarify, his ultimate will have an indication when a target can be executed but it can't leave the target even if they are safe from execution. That's why his ultimate is named "Merciful" and is just part of the gamble. To help ensure you execute your target before they heal is where his E ability comes into play. I was thinking he should gain a burst of movement speed at least equal to Udyr's E when Udyr is fed and has the needed items (Guessing it would be around 800 move speed).
Maybe there is too much in his kit that benefits him, if so leave a comment explaining what the ability is and why it's too strong.
