Note: This can only be done in unpatched versions of the game. After acquiring new talents, meditate to distribute them. After you come out of meditation, go to the Hero panel and right-click on the enhancements you just used the talents on. You will hear the money sound, but no visible change. You can meditate again and have those talents back, and will still have the enhancements you had previously used the talents on.
Note: This can be done as of patch v1.2. There is a small crevice between the fence and a small hut to the top left corner of the field. Use this to use potions or regenerate health. Neither the dogs nor Beast will be able to get to you as long as you stay in this opening. Do not worry about the villagers or Abigail, as the dogs will not attack them. If you have upgraded Ard Sign for STUN, it makes the fight a lot easier. Aim for Beast and cast your Sign. If he is stunned, simply do an auto-attack and you will trigger a one-hit kill.
