Draconic Fury

You have honed your dragon companion to become a formidable adversary. Your dragon companion gains the following;

• Elemental Strikes - When your dragon companion makes a melee attack, it can choose to deal an extra 1d6 damage of it's breath weapon's type (fire, cold, lightning, acid, poison, etc). It can use this feature a number of times equal to your proficiency bonus and regain all expended uses on a long rest.
  
• Breath of the Abyss - Once per long rest, when your dragon companion uses it's breath weapon, it can cause the area to become hazardous terrain for 1 minute. Creatures within the area must succeed on a dexterity saving throw or take 1d6 damage of it's breath weapon's type. If your dragon companion uses both it's breath weapon and Breath of the Abyss in the same action, creatures within the area only need to make one dexterity saving throw to avoid taking damage from Breath of the Abyss and half damage from it's breath weapon. The damage increases to 2d6 damage at 5th level, 3d6 damage at 14th level, and 4d6 damage at 20th level.
