Disciple of the Dragonqueen

You call upon the power of Tiamt, the Chromatic Dragon, to magically transform yourself into a divine archon of the mighty dragon.

You assume the form of the Archon of Tiamat presented in the stat block below for the spell's duration.

Your game statistics are replaced by the statistics of the archon, though you retain your alignment and Intelligence, Wisdom, and Charisma scores. You also retain all of your skill and saving throw proficiencies.

You assume the hit points of the new form. When you

revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn't reduce your normal form to 0 hitpoints, you aren't knocked unconscious.

When the spell ends. You lose all remaining spell slots you had before you assumed the archon form, you also take one level of exhaustion and are incapacitated for one round.

You retain the benefit of any features from your class, race, or other source and can use them. You can't activate abilities of,use, or wield your weapons.
