Divine Aberrant Dragonmark

Through training, luck, hardship and sheer determination, your dragon mark, blessed by a deity, reaches its complete form. You gain the following benefits:

• Increase your Constitution score by 2, to a maximum of 24.
• Choose one 6th-level, one 7th-level, and one 8th-level spell from the sorcerer spell list. You learn these spells and can cast them through your mark. Once you cast a spell, you must finish a long rest before you can cast it again through the mark. Constitution is your spellcasting ability for these spells.
• When dealing fatal damage to a creature, you gain temporary HP equal to half the creatures total health to a maximum of 100 HP.
