Any attempt to attack the character will be with disadvantage, including ranged attack spells (i.e. magic missile, fire ball, etc.)The skeletons will defend the character by acting as a shield. The skeletons will remain within two feet of the character. Due to the proximity of the skeletons, should the player choose to attack with a melee weapon, it will be at disadvantage. If one of the skeletons is killed, a replacement will arrive on the next round by coming up from the ground and take the position of the dead skeleton. If attacked while in transition from the ground to the standing position, any savings throws will be at a disadvantage and melee attacks on the skeleton will be made with advantage.
