Nakudama's Electric Bloodline (TP)

Although it's uncommon in today's day and age, some Nakudama are able to awaken the now dormant skills held by their warring ancestors. You gain the following benefits:

• You have resistance to lightning damage.

• You have an electrified tongue that you can use to make unarmed strikes. It has the finesse and reach properties, and when you hit with it, the strike deals lightning damage equal to 1d6 + your Strength or Dexterity modifier, instead of the bludgeoning damage normal for an unarmed strike. The damage from your tongue increases when you reach 5th level (1d8), 11th level (1d10), and 17th level (1d12).

• When you become grappled by a creature, you can use your reaction to force the creature to make a Constitution saving throw (DC 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 lightning damage and the grapple ends.
