Mirru the Grand Puppeteer [Champion Concept]

DISCLAIMER I will at no point update this post with damage values, mana costs, cooldowns, base stats, etc. as that is the role of the balance team

So I had an idea for a rather unique champion. Think of him as a combo of the old and with a hint of .

Here is what i have so far

Passive: (Mental Fortitude) Mirru has an additional resource instead of mana known as Mental Fortitude. The base Mental Fortitude is equal to (%hp). He does not gain health from items but instead increases his Mental Fortitude, nor does het gain armor and magic resist from items but instead will gain base health equal to (%) of the total. Taking damage from non-champions will deal damage directly to his health pool. Taking damage from an enemy champion deals damage to Mental Fortitude before damaging his health pool. When he has no Mental fortitude he briefly becomes feared. While feared his marionettes gain bonus attack speed, wonder aimlessly and attack random targets. After not taking champion damage for X seconds he begins to regain Mental Fortitude at (% hp/5 sec). Health regeneration is split evenly between Mental Fortitude and his health pool unless his health is full, potions will heal his health first. Using abilities cost Mental Fortitude.

Whenever he first uses an ability it summons the corresponding marionette, once summoned using an ability commands the marionette to attack.

Q: (Enoc) Enoc's first attack against a non-champion target causes a small cone of damage to strike all targets behind it. When Enoc first attacks a champion he will briefly slow them and causes the next attack from a marionette to not apply the cc.

W: (Piton) Piton's first attack against a non-champion will cause him to strike it rapidly for (x) number of times. When Piton first attacks a champion he will briefly root them and causes the next attack from a marionette to not apply the cc.

E: (Gerdeg) Gerdeg's first attack against a non-champion will strike all targets in a straight line behind it. When Gerdeg first attacks a champion he will briefly silence them and causes the next attack from a marionette to not apply the cc.

R: (Pull the Strings) If an enemy champion has been struck by all 3 marionettes, within a small window, Mirru can activate this ability to temporally take control of them and activate one of their basic abilities by activating the corresponding marionette. Even if their ability is on cooldown, this ability is considered to be friendly to Mirru. (for expamle ahri's charm will charm one of her teammates shen can taunt his own team and so on. Darius's Q will still heal him if he hits a character friendly to him.) If the ability kills the target it counts as a kill from Mirru not the "puppet". Mirru can not move his puppet.

So that is what i got so far. I am a terrible artist so dont expect a rendering. Any feed back regarding his kit would be greatly appreciated. I will be checking in frequently to update his story and possibly change the abilities.
