we are now in Past Glory Stage2. this stage is MUST to be achieved. (hospital capacity +100%) you can get crusader resource chest per 10 barbs. it is also good reward. luckily(?), we have the event "race against time". make sure you do all…

I check how many gem I need when I train troops, and compared between "new(0 to T5)" and "upgrade(like t4 to t4)". the amount of gem is the same as the "time" for train. this is the result. in total, "t4 → t5" is much faster than "t1 → t4"…
