The fight against this boss is probably the most arduous task in the game and is divided into three phases:

Phase 1

The first phase will have the monster at its full size and in full-on attack mode. Attack with all you got and use the Dragonator to move onto Phase 2.

Phase 2

Gaismagorm will be at a lower level in the second phase, but its attacks won’t let up. Try to stay under its feet. That way, you will avoid spitfire, explosions, and fiery rein. 

Phase 3

As you deal more and more damage to this colossal enemy, its health will degrade, and will finally start the last phase. 

In it, the boss will change into frenzy mode. Enraged, it will start shooting fireballs out of the body.
