1.    "Grab On": Tightens your grip so you won't fall down. This actually increases the buff on you, to prevent it from reaching 0. You can increase the buff up to 99.
2.    "Dodge Claws": Attempts to dodge the Wyrm attack. This ability is off the global Cooldown, meaning you can use it as "interrupt" to the Wyrm attacks, however it will be deactivated a few seconds after you use ability 4.
3.    "Thrust Spear": Normal attack: you attack the Wyrm, causing damage
4.    "Mighty Spear Thrust": You use your spear to attack the Wyrm. This has a Dooldown, and it also makes ability number 2 be on Cool Down for a few seconds.

 

o    The catch is, of course, that you will have to use ability number 4. If you don't, eventually you will fall off the Wyrm, because Ability number 1 stops being useful after a while.

o    Therefore you should use spear attack (number 4) ONLY after you dodge his attacks, and while the cool down on ability 2 is on, use ability 1 to avoid him attacking you as long as the cool down is activated.

1.    Start with normal attacks (3) and Garp Ons (1) when needed.
2.    As soon as you see the attack warning press 2 and dodge his attack.
3.    Immediately press 4 to make a special spear attack
4.    Repeat ability number 1 till the cooldown of ability 2 Ends.
5.    Go back to step 1
 

o   Eventually he will pick you in his mouth and phase 1 ends.
