|Objective|| Plant explosives on gates |
Protect Source Well
|Enemies|| Clockwork Soldier|
Day 21 objective is to plant explosive charges on both gates of the nomad settlement, by getting past the Clockworks guarding it and interacting with the gate. There are no more clockworks than what are there at the beginning of the day, and none of them go to attack the source well. This day has no Build mode and the same Kingdom Force units are there, if they survived the previous days.
With the generous time limit and no attacking Clockworks, this day is very easy.
