Oh, so sad for her... :'(
The sparring is good, especially if she wants to be a Master Vampire and it could help her to increase her skills and gain enough point to get new perks.. My Sim got Vlad as her mentor and she sometimes visits him to get mentored or just playing the pipe organ (since she can't sleep). Sometimes, Vlad will come over to her house to mentor her too... And if you want to win the combat, you will win easily if you have a full rank of the vampiric strengths...Besides than that, I also randomised my Sims powers & weaknesses, not only for fun, but I would like to have unpredictable Sims.. and funny enough, one of her powers is a sun resistance, but on the other hand, one of her weaknesses is a Day Phobia... :#
