Tuathan

Your fey bloodline has been unlocked. Drawing on your fey ancestry, you can transform into a tiny Feywild beast. You gain the following benefits:

• Increase your Dexterity, Constitution or Charisma score by 1, to a maximum of 20.
• You learn to speak, read, and write Sylvan.
• When you gain this feat choose one tiny, earthbound animal. You gain the ability to shapechange into a fey version of that animal or back again at will, as a bonus action. You retain your statistics, and may speak in this animal form, but you loose your attacks and ability to cast spells. You gain a bite or claw attack, using your unarmed attack bonus to hit and dealing 1d4 + Strength modifier damage. This damage increases to 2d4 at 8th level, 3d4 at 11th level, and 4d4 at 14th level. While in this form you also gain a +5 bonus to Dexterity (stealth) checks.
• You gain advantage on Constitution saving throws.
