The new “free finish” function allows you to complete ongoing building upgrades with a remaining duration below 5 minutes free of cost.
The function can only be used 15 times consecutively until a cooldown starts. During this time, you cannot complete buildings via “free finish”. After the cooldown, you can use the function again.
Complete all buildings (building list)
The “free finish” will be taken into account for the “complete all buildings” function in the building list. For all buildings that can be finished free of cost, no gold will be deducted as long as the limit has not been reached.
Cross-castle upgrades (mass function)
If you speed up or finish buildings across castles for gold, the “free finish” function cannot be used due to the multitude of habitats.
Info: The “free finish” function cannot be used in global buildings (ruby storage, etc.).
