You have formed a bond with the other members of your adventuring party - a bond so strong it allows reality to bend.  You gain the following benefits.

• One ability score of your choice increases by 1.
• At the end of a long rest, you can designate up to 6 party members as your Fellows.  As an action when you can take damage, you can create a psychic scream.  Each of your Fellows that are within one mile of you can hear this scream, although no other creature can.  Your Fellows that hear this scream have their walking speed increased by 30 feet until the start of your next turn, and they gain advantage on all attack rolls they make before the start of their next turn.  You then gain a level of exhaustion.  You can change which creatures you count as your Fellows at the end of a long rest.
