How to counter Sated Devourer
- Take all the scuttle crabs. They give 2 stacks to the jungler, and almost any laner can easily take them.
- Ward their jungle and invade. Give them a hard time. Last hit their camps. Deny them stacks.
- Take dragons, or ward dragon and don't let them take it. It gives 5 stacks.
- Build thornmail, frozen heart, randuins, etc. Cripple their attack speed and you greatly reduce their DPS.
Basically, delay their powerspike and outscale them. Make sure to have key defensive items on your team when they finally get 30 stacks.
