Equip gear that boosts your fire resistance

Exploit Great Wyrm Theodorix's weapon type weaknesses

Equip gear that boosts your fire resistance

Great Wyrm Theodorix has several fire attacks that can deal a lot of damage if you're not careful. The fire can also stick to the ground for a few seconds, limiting your movement in the boss area.

Equip gear such as the Flamedrake Talisman to reduce the fire damage you take. You can also use Fireproof Dried Livers to temporarily increase your fire resistance.

Attack Great Wyrm Theodorix from behind

Theodorix has lumbering attacks, making it easy to outmaneuver and reposition yourself behind it. This will be the safest spot to attack it from since its moves mostly deal with its front area. You'll only have to worry about its spinning attack since this can reach you.

Exploit Great Wyrm Theodorix's weapon type weaknesses

Theodorix is weak to most physical damage types, namely Standard, Strike, and Pierce. Use weapons with these damage types to deal increased damage to it.

Avoid using elemental and Status Effect weapons since Theodorix has high resistance to many of these.
