DescriptionThe Cathedral is a miscellaneous building that costs 25,000 gold. It's unlocked at level 23.
After you complete the Cathedral, you will need a lot of help from friends: must fill 12 slots (or buy a slot for 3 Cash each) before be able to training Monk units.
You can train monks inside the Cathedral, and each monk cost 2000 meat 1000 gold. Monks can convert enemy units into yours, but the attack delay is 60. The most powerful units I know monks can convert so far are draggies. You cannot convert monsters or anything more powerful than that.
