Boon of Liquid Titanium

I'm going to burn you to the ground. When I'm through with you, your axe will be the only reminder you ever lived.

You awaken your mother’s titanium blood as your father’s divinity protects you. Liquid titanium flows through your veins and your body becomes flushed with liquid titanium. You gain the following benefits:
•. You are immune to Fire
•. You are immune to damage and effects from Titanium weapons
•. You gain 10d12 extra hit dice
•. Your weight increases by times 16
•. Flaming Swordsmanship. When you hit with a katana (any flavored or named katana) weapon you may deal an extra 2d6 fire damage
•. You gain a Dragon Form

Dragon Form. As a bonus action you transform into a titanium dragon until you use a bonus action to end the form. You keep your statistics except you increase in size to Huge. When you transform, you choose whether your equipment falls to the ground, merges into the new form, or is worn by it. Worn equipment functions as normal. Worn armor that is Merged becomes Natural Armor retaining all benefits. Choose one melee weapon it becomes a claw attack with Reach and base damage that deals titanium slashing. Choose one ranged weapon, as an action you can breathe liquid titanium in a 120 ft by 10 ft line. Roll for damage the ranged weapon would do on a hit. Each creature must make a constitution save against your spell save DC. On a successful save the creature takes the damage as fire damage. On a failed save each creature takes twice the damage as fire damage and the creature begins to become magically encased in titanium and is restrained. It must repeats the saving throw at the end of its next turn. On a success, the effect ends. On a failure, the creature is petrified until freed by the greater restoration spell or other magic.
