When spawned, medusa will spawn 5 snakes that are slow but strong and defencive. When these 5 snakes are killed, medusa will then b able to move. Also she can turn things to stone for 3 seconds(cooldown till next use 10).
Advantage:
Have an annoying base that has high leveled defences? Just let your snakes die and watch medusa turn them to stone....hopefully....
Disatvantage:
When medusa is not moving she can still be targeted by clan donations and she cant attack back till her snakes die.
Stragedy:attacking:
Attack sides with weak defences and then spam giants.
Stragedy:defending:
Pesky trespasser using medusa? Make a smalle spot in the middle of your base where they can spawn troops. Put some archers close to it and other defences near the outside.
