Aric is unsure how to proceed. He sees the dogs, and knows he should talk with them, but there are still guards. Not having any more spells, he figures he might as well just go and chat with them. So, he proceeds to cast a ritual way from prying eyes and moves closer to the sleds with a childish eagerness.
As he approaches, he'll ask the guards: "sirs, can I pet the dogs?"
@Steve Gorak You're approaching the bearded Reghed tribesman tending the dogs. This would normally be an automatic or very easy check (dc 5), but because they're on alert it will be a tricky (DC 12) Persuasion check. Success gets permission to approach dogs. Failure means he tells you to leave them alone.
p.s. @Neurotic I screwed up the DC of your Deception check, should have been 12 instead of 15 cause I forgot that I use these revised DCs. But with your low roll, outcome would be same. Just fyi.
Aric seems disappointed. He bolts back to the tavern to get with the others. He'll need help to approach the dogs. He explains that he needs to talk to the dogs to convince them to delay the caravan's departure. He needs help because he's not a people person.
