Generally speaking a Dex + Stealth or Wits + Animal Ken check is a good thing to use when trying to surprise a prey animal, but I'm not going to worry about it here. Do remember the transformation to wolf form requires another Vitae.
In wolf form, Aesop is able to sneak up on the deer and bring it to the ground. Meanwhile, the other runs toward Jayant, unaware of his presence.
The deer has 8 Health. The blood of large animals provides 1/2 Health dots in Vitae, i.e., a full grown deer provides 4 Vitae.
