Random Custom Builder

Random Custom Builder (RCB) Edit

Random Custom Builder, also known as RCB, is a unique builder only available in Classic mode, unlocked at Prestige 5. With this builder, 6 random units, 1 from each tier, are assembled together into a builder fitted with a random builder's racial passive, to be used throughout the whole game. Due to the variability of the type of units (i.e., bad balance of melee tanks among fragile DPS), the units may synergize very poorly and require higher investments in defense in order to hold the waves properly. Thus, the Random Custom Builder may well be largely dependent on luck just as much as skill in order to compete with preset builds.
