Xanin notices the sheeps apprehension and approaches the massive Uriak. He takes a moment to pet the sheep that he's been playing with all day and then, extending his arm, he grasps Hath by the forearm in welcomed greeting,
"We have only just met, but I have a good feeling about you lot."
Before their handshake comes to an end, Xanin winks and whispers,
"Maybe this will help the sheep recognize that you are friendly strangers," and then unexpectedly pulls the barbarian into a full embrace ... well actually that's what he intends, but the large bulk of the hulk doesn't budge and instead he pulls himself into the barbarian.
After a moment, he releases the hug with a silly smile and turns back the sheep for another pet.
OOC:
Trying to provide Hath with advantage on his roll without burning my spell slot. Let me know if that would work. If I sense the message isn't getting through to the sheep, then I'll cast my spell to explain so the message is clear.
