Turmo’s Arm: Use shield and block Turmo’s arm advances towards you. Wait for when the mini boss to prepare it’s attack. You can attack the boss without getting hurt yourself.
Turmos the Evil Overgrowth: Now you are fighting your first real boss. This boss can take a while. The safest route is to take down each of the arms slowly to deal minor damage to the boss. However, if you have plenty of health and ammos, consider taking out all of the arms. The boss will start sucking the air around, keep your distance and use yours bombs on him. When you get sucked in you will take 2.5 heart damage so be very careful.
After killing the boss, Rigger will show up and say that he will move in to settle in the forest. Talk to him again to get the location of the Riptide Riff. Lastly, once you set sail the hermit messages you via the shell. Visit the Hermit’s Island again.
