How to play

Early game · first 8 minutes
Use Splatter and Puddle Punch to control the wave and move enemies off the angle they want. Save The Cube for the teammate who is actually being focused. Take clean farm when it is available instead of treating support utility as a permanent farm rule.
Mid game
Use The Cube to save a threatened teammate, Puddle Punch to move the diver, and Splatter on the ground the enemy wants to occupy. Save Goo Ball for an engage where it can affect the fight rather than using it on a routine lane exchange.
Late game
Use The Cube for the save and Goo Ball for the larger teamfight after enemy movement has been spent. If both are unavailable, use Puddle Punch and Splatter to control space until the bigger tools return.
