@ctme2000 love it, I thought Aid was for skill checks only but it actually works for attack rolls - you have a chance to turn this from a miss to a hit :D please take the Aid reaction and describe it as you see fit. I'll let you run with it - this is just a large rat lol nothing special, they're rodents, and use their sharp teeth as their primary weapon. In large numbers and extended presence, pestilence may be a concern, but not in this situation.
I should add: I'm totally down to adjust the DC based on how creative you are in aiding Wugruk's attack ;D
