Jri - The Jaunter

So the basic idea is that Jri does not have a basic attack but instead her kit make her moderately mobile and her skills are very very spammable but deals little damage. This idea is based off the main character of Transistor by supergiant games.

She should be pretty squishy and uses a sword/gun hybrid like Transistor.

Passive: Agility (suggest name please): Jri has no basic attacks; Instead, each champion kill or assist will increase her movement speed by 5 - 10. Jri has a new resource called Memory which replenishes in chunks (much like reneger) at the rate of 1 every 5 seconds for the maximum of 15 memory.

Q: Ping No cost: Jri uses the cannon at the back of her sword to fire out thin bullet that deal 5/10/20/25 damage + 0.2% ap to the first enemy hit and enemies in a very small radius (20px). Jri does not have to stand still when casting Ping. This ability is meant to replace her basic attack, very spammable but little damage. I'm not very good at stats so please suggest scaling and base damage. This is like ping() + spark() in transitor

W: Shell 3 memory 25 seconds cooldown: Jri surrounds herself in a reflective shields that reflect the first ability or basic attack. This shield last 0.25 - 0.5 seconds before disappearing.

E: Null 2 memory 2 seconds cooldown: Jri targets an aoe area and nullify any enemies hit, reducing their amor and magic resist by 5 - 7. This effect stack up to 3 times and disappear after 5 seconds

R: Jaunt 5 memory no cooldown: Jri dashes a short distance to wards the cursor. up to 3 consecutive cast can be done immediately, providing that you have enough memory.
