The first tip is the overlap of the builders : if an improvement takes a day due to the overlap of the builders will halve the time based builders employed on building improved .
Then the improvement of the builders up to level 3 : thanks to this improvement decreases the cost and time of the improvements .
Builder lvl 1 : time 0 % 0 % costs
Builder liv 2 : time costs 5 % 5 %
Builder Level 3 : 15 % time costs 15 %
Then the factory of the mergers of the troops that come together for a limited time : ie we can combine the troops for a limited time that depends on the improvement of the factory .
Es : We combine Archer Dragon + = An archer The dragon with the power of both.
Thanks if you appreciated my ideas .
