Elixir of Draconic Essence

This elixir comes in five varieties, one for each of the five chromatic dragons. Made from the blood of true dragons and enhanced by magic, the elixir grants powers of its associated creature to whomever drinks it. Thick scales of the appropriate color cover the drinker's skin, granting him a +4 enhancement bonus to his existing natural armor bonus. Meanwhile, his physique grows in power to match his draconic form. He gains a +8 enhancement bonus to Strength, a +4 enhancement bonus to Constitution, a +2 enhancement bonus to Intelligence, and a +2 enhancement bonus to Charisma. His face extends into a fierce snout, while his fingers twist into sharp claws, giving him 2 claws and a bite he can use natural attacks (damage is based on size, see the Dragon Essence table). Powerful wings burst from his shoulders, giving him a fly speed of 60-feet (average). He gains a breath weapon of the appropriate type (see the Dragon Essence Table) usable once every 1d4 rounds, dealing 6d6 points of damage. A DC 14, Reflex save halves this damage. The drinker also gains complete immunity to the energy type associated with his breath weapon. These effects remain for 10 minutes.
