Flothaboss should design a base that has 300 forges on each and every tower/obstacle/ unit used (100 each perk). Players are able to attempt once a day but will use up max food count whatever their max silo capacity is. No scrolls or revive allowed.
The base design changes once a week.
In other words, players have 7 attempts to do the challenge (once a day before the base is changed again), and rewards shall be given upon success. (Once successful, no more attempts can be done).
