Jailer in the Morgue is the last stage in Alcatraz.
Dober P.D, the boss, has a 33% chance of creating shockwaves like Kory - you will need some luck to win this battle. Pray that he won't trigger waves, and constantly hit him with high-damage units. As he requires a long time to defeat, prepare yourself to face many shockwaves.
Since Dober P.D doesn't have any type, don't bring any special effect units.
It's highly recommend to take a rich cat on three star.
If you bring two research combos, Paris cat ( 34+1), Ramen cat (28+4) Dragon cat (20+7), wall cat (20+9) And Jamiera cat (20+15) + other heavy attacker you have you will easily win.
