Tips for killing Douma
- You should left/right dodge after you launch an attack since Douma will launch the ice attack after you hit him with forms like Flame Breathing 2nd Form or Thunder Breathing 2nd Form.
- If you're low just keep running.
- Get your hunger bar at least a half before entering the battle.
- Start with m1s at the start of the battle.
- Run around him , and attack with m1s, after you are finished run around him and then repeat, you can also use some moves while doing this, but make your you run as fast as you can when your move is finished. 6. You can easily kill with any rank and thunder breathing just run and spam thunderclap.
- Keep walking around and hitting him, doing this the boss doesn't hit you and it is rare for him to use skill, you will chee se the boss, not needed an HYPER rank, it is not the fastest method but the most safe
- When low on hunger or HP, keep running and throwing in some 1st forms or something to slow Douma down.
7.You need to not use breathing and just run around him.
