Fey Magic S Strong

With Fey Magic, R first cast triggers Vulnerability multiple times. Huge damage.

Build around Fey Magic + Ornn's first R hit. Fey Magic procs Brittle 4 times on first ult — Brittle's 18% max-HP magic damage stacks four ways for 72% max HP, then magic pen + amp items finish the kill. Forge: ability haste > magic pen. At ~500 haste, Fey Magic is ~15s CD and ult is ~16s — every fight is a nuke. Build straight magic pen + damage amp.
