New champion concept

Passive: Links to allied champions in a radius whenever a spell is cast for 4 seconds. Basic attacks link to enemy champions and big monsters for 2.5. When linked, allies share your HP and Mana regen (along with any other mana/healing sources) for the duration at a percentage. Linked enemy champions receive damage based on a percentage of what the champion herself receives for the duration.

Q: Tosses a nail forward dealing AP damage to the first enemy hit and linking to all the other enemies close by. Enemies linked together are slowed for the duration (or until out of range of each other) and share damage at a percentage.

W: Creates a totem at an area that lasts 7 seconds. All skill-shots and AoE attacks that hit it raises the amount of damage it could store (at a cap + AP). After it reaches the cap (or 7 seconds) it explodes and deals damage split among the amount of enemy champions hit. Basic attacks don't fill the meter, and while it doesn't block skill-shots, it does count as an allied/enemy champion.

E: Creates a semi-weak "shield" around the champion. If it isn't broken, the Champion doesn't receive damage. If it is, it stuns enemies around her and all the damage goes through at once, damaging the champion in a chunk.

R: Channels for a bit, then curses the ground around you. Champions caught in the AoE have their armor/mres reduced and mimic the movements of the Champion for the duration. This acts like a root otherwise and also applies the passive to everybody inside (possibly doubling the effect).
