Sofi the Nanotech (New Champion Concept imagined with the help of a friend)

So far the ideas for this champion before i type out the kit are as follows. Her name for starters was inspired by a friend who pointed out this name means Wise or Wisdom in greek which i thought was pretty cool and went with that. I will update further for possible lore introductions and more later depending on how well this is liked. This is also my first time trying this so go easy on the critique. Anyways here it is

Passive: Nanorobotics OR Nanomytes. Whenever a skill is used by this champion that affects allied champions they are given a small buff of Armor and or Magic resist for a 3 second duration. (This passive buff cannot be extended by her E)

Q Drones Assistance: Summons forth a automated drone that can also be manually overridden by this champion. When Drone is summoned, champions around are healed for 50-95 health+ scaling AP. The drone then creates nanobytes that heal over time after the intial burst of healing receive regeneration over time healing for 10 health every second that scales with skill level and ap. In order for her other skills to be usable Her drone must be in play. (Requires to spend mana per second to keep drone active)(The drone unless its being controled directly automatically moves to the lowest healthy ally champion in range)

W: Nano Repair Her drone gives 1 target ally a burst of nanomytes for 3 seconds. During these 3 seconds 30% of the damage taken to be refunded instantly. Targeted champion will receive a debuff called Enhanced Immunity. During this time this champion cannot be buffed by this ability for an extended duration but in exchange is granted additional tenacity for this that decays overtime. During this time target cannot receive health regen from Drones Assistance.

E Drone Reconnaissance: Activates the drone within a limited area to instantly scout and area on the map where there is fog of war. For each champion spotted while its granting vision for a short duration gives a bonus duration of effect to Nano Repair and Take and Give. Healing from Drones Assistance is disabled till the drone returns.

R Take and Give: Places the drone in a Circular area in a limit vicinity that slowly drains health from enemy champions and slows them by 50% while in the area of effect. Ally champions in the area of effect receive a shield of base 75-150 depending on how much hp they are missing and additional shielding based on how much hp was taken from enemy champions. Zone Lasts for 5 seconds.
