Playing against Swain

How to counter and exploit weaknesses

1

Stay out of his R drain range — if you can't burst him, back off and wait for R to expire.

2

His E root triggers on the RETURN: dodge the returning projectile, not the outgoing one.

3

Grievous Wounds reduces his R drain and passive heals — buy it early.

4

Swain is vulnerable to long-range champions who can poke him without entering his drain zone.
