How to play against Rat King

Combo: Rat King plants Rule, Ratannia!: his team gets speed, slow immunity and 15% damage reduction within 20m. Then he slams it, knocking up and slowing everyone in his line of sight within 20m, and rats swarm out applying Rat Swarm.

Punish window: After the slam his ultimate is down for a long time (160s base).

Beware: Break line of sight before the slam, and don’t clump inside the banner’s 20m. Stay out of his short shotgun range.
