Custom is unique in which it requires prestige instead of levels or arcade mode. Unlike the other builders Custom can only build egg towers at first. When players unlock each other builder as normal, they may implement a tower from their unlocked builders into the custom menu.
While Custom builder does not have a tower boost ability, it's ability to build from a variety of choices gives it an advantage over other players. Has a 20% reduction in everything.
Customizing Tower OptionsEdit
Each tower has a value corresponding to how much the tower contributes. Each tower also has a corresponding tier catagorie. Custom allows a maximum build choice of 13 ratings and 1 tower per tier.
Note: Tier and Rating are only used for custom and has no meaning elsewhere.
CHANGE: now it seems the max value for towers for custom builder is 10 not 13
