The Builder Recruitment is an item that allows the governor to hire a second builder for two days within the city so that two buildings can be upgraded at the same time.
While this item is useful in the very early game, most governors seek to reach VIP Level 6 as quickly as possible to permanently unlock the second builder slot, rending this item unnecessary. If a builder recruitment item is attempted to be used after VIP Level 6 is unlocked, it will automatically be replaced with a Building Speedup (60m) item.
|Builder Recruitment||Activates the second building queue for 2 days or extends it by 2 days (VIP 6 can permanently unlock the second building queue).|
You will get approximately 3 Builder Recruitments before getting to City Hall 10 (Haven't recorded where the source is). Therefore, it is important to use this item all the time and rush for VIP 6.
