Prerequisite: Warforged, Level 4+

You have tapped into the arcane power that gives you life, allowing you to produce a number of magical effects. You learn one cantrip of your choice from the sorcerer spell list. You also learn the enhanced ability and levitate spells. You regain the ability to cast these two spells in this way when you finish a long rest. Constitution is your spellcasting ability for all three spells.
