- Conditions: HR 10 or higher
- Failure Conditions: Time expires, Faint 3 times, Fail to guide Zorah Magdaros
- Notable Reward: Commendation
Start by using a wingdrake to land on Zorah Magdaros' back. Be sure to grab some stone near your landing spot for later. Go straight and you should reach one of Zorah's Magmacore. Destroy it making sure to dodge the lava spewing from it. The Magmacore drop a material on destruction.
Head for Zorah's "tail" and go down until you find a cave with another Magmacore, destroy it.
Now make your way all the way up Zorah Magdaros body, climbing from the left flank, you should come across a big magma rock, you can destroy it for 30RP.
Once at the top you can jump down some kind of well where the last Magmacore stands, you can destroy it now but it's possible Nergigante show up before that and you'll have to come back later.
Go take care of that weak version of Nergigante, it will flee after enough damage be done to it, you then need to destroy any remaining Magmacore.
Once all Magmacore are destroyed, wait for a Wingdrake to bring you on the Barrier. You can find another rock to break on Zorah's right flank while waiting.
On the Barrier, load cannons and fire, making sure to line up the cannon with Zorah's position, try to fire 5 cannon balls at once to exhaust Zorah Magdaros. When there's no more ammo, switch to another cannon.
At some point, the Field Team Leader will talk about the Dragonslayer, don't use it yet, keep firing the cannons, moving toward the boat little by little.
When ?NPC? says Zorah Magdaros is charging up for a big attack, use the lever on the boat to activate the Dragonslayer and stop Zorah's attack.
After this, it's just a matter of time and cannon balls until Zorah Magdaros gives up.
