Reload TimeHero Lore
The cryptid ruler of the New York Warrens, The Rat King towers over his subjects in size, strength, and ambition. No longer content with hiding underground, the king has revealed his bold vision for a future where he and his subjects can walk the surface without fear of the pest control vans that roam the streets of New York (or as the rats call them: human death squads)
Step 1: Take control of Long Island Step 2: Declare Long Island as the new sovereign nation of Ratannia Step 3: Execute every human that refuses to leave this new rat utopia
But air tight as this plan is, the king of rats didn't want to take chances: and so he’s decided to the summon the patron to help hedge his bets.
Recommended build for Rat King
Rush 4.8k, focus on yellows/tankiness early, then scale into heavy DPS with Juggernaut/Unstoppable resilience.
Early Game
Buy L-R. We can focus on yellows because Rat King is tanky af. Rush to 4.8k as fast as possible.
CORE
Buy L-R. You can get Juggernaut if you want to become a bigger tank than you already are. But I prefer focusing on some DPS.
Late Game
If you are struggling then you can get Unstop early.
Early Game
OPTIONALBuy whatever is needed.
Mid Game
OPTIONALGet your greens!
