As with the first encounter with Zorah Magdaros, having high fire resistance will mitigate damage from its magma cores. Wear Kulu, Anjanath, or Rathalos armor pieces to increase defenses against the element. Be sure to eat a veggie platter to further boost fire resistance.

Stock up on as many healing items as you can, as well as nullberies, to increase survivability.

Zorah Magdaros

This quest has a few differences from the previous Zorah Magdaros battle. First, you will automatically begin the fight on Zorah Magdaros’ back. Quickly take out the magma cores marked on the map to weaken the monster.

Zorah Magdaros Monster Guide

Be on the lookout for stalagmites above which the fleet has rigged with explosives. Shoot them down with your slinger to do extra damage to Zorah Magdaros.

As you down the magma cores, Nergigante will appear again. Since other hunters from the commission are tasked with handling it, you can just ignore it. Continue destroying the remaining magma cores and dropping stalactites on Zorah Magdaros.

When Nergigante leaves, the commander will give the signal to commence the final skirmish. You will automatically be taken to the barrier platforms by a wingdrake. Run to the ballistae or cannons and load them up to fire at Zorah Magdaros. Move to another artillery piece when you run out of ammo.

When Zorah Magdaros is close enough to the barrier and attacks it, run to the left side of the platform and drop down to the ship below. Use the dragonator to deal massive damage to Zorah Magdaros by pressing the switch on the ship’s deck facing the barrier. You can then choose to get back up on the barrier platform using the wingdrake or pepper the monster with artillery from the ship.

Continue bombarding Zorah Magdaros with ballistae and cannons. While waiting for the dragonator to be usable again, you can use the one-shot binders to interrupt Zorah Magdaros as it winds up to smash the barrier. One is found on the right side of the barrier platform and another on the side of the ship facing Zorah Magdaros.

Mine Zorah Magdaros’ Back

You can obtain materials to craft Zorah Magdaros equipment while on the monster’s back. Be on the watch for ore deposits while searching for the magma cores.
