Griffin Conservatory is an Adventure Map location, and commonly known as one of the creature banks. It is guarded by 50–200 griffins. As a reward for defeating the griffins, 1-4 Angels will join the hero's army. The more griffins there are, the more Angels will join.
As with all creature banks, the hero's troops are located in the middle of the battlefield surrounded by enemies, and War Machines are not available. The guards are divided into five stacks; one in every corner and one in the middle of the right edge. The stack in the left lower corner may consist of Royal Griffins. Slain enemies do not respawn (should the hero retreat or be defeated).
