I think that I have already played this scenario, but I have vague memories of it being rushed. If you are fine with someone playing for fun. If a level five would not bump the group into mid tier. Then I will be happy to bring Dr Arkadius. He is a fifth level Necrocultist who is a healer and a summoner who can also deal with undead. If you would rather that I pass, then there are no hard feelings and I wish you good luck and good gaming.
