How to play as Gwen
Let Teemo push early and preserve health; wait for his blind to be used on a minion or block it with W before committing to an auto-heavy trade.
After level 6, use R's slow to stay on Teemo, but check the chase path for mushrooms before running him down.
Teemo Q blinds basic attacks, while Gwen W can prevent a targeted blind dart from reaching her when Teemo stays outside the mist; Gwen Q and R remain usable during a blind.
