Embrace of the Pit

Crepusculum Kingdom Bonus!

Once per long rest, use your bonus action to cause two large skeletal arms to burst from the ground at a point of your choosing and grasp at the nearest creature, which must make a DC 16 Dexterity save or be restrained by the arms (restrained = speed 0, atttack rolls against creature have advantage, creature has disadvantage on attack rolls and Dex saves). The creature can make the save attempt again at the end of each of its turns to free itself.
