How to beat Annie as Cassiopeia: the early game

This lane is a pure skill matchup through level 5 — Annie's stun timing dictates every trade, and if she catches you with an unexpected 4-stack proc she can burst you down before you get a Twin Fang stack going. Careful stun-tracking and poking from max range with Noxious Blast is how you survive to your power spike. Track Pyromania stocks after 4 casts and she starts the game holding it — the glow under her feet is the tell, not the cast.
