Check out my previous Post on Van Helsing, should be under game strategy, and you will find the sequence of quest n how many times you need to charge it.
Stock up on skulls, aspen leaves, bullets n garlics. The quantity required is gigantic.
what happened during the first full Moon event was that the monster appeared when you had a quest for it. For example, banish 10 zombies, then you will have a zombie I'm your manor. I have learnt from the seniors here that you can keep the zombies in your manor for others. First banish 9 zombies, then visit friends. When you see 2 zombies in friends manor, then you banished him. In this way, when you return to own manor, you see the zombie is still there. Otherwise, he disappears.
Generally, a tip is to visit the players on the rating list n find weakened monsters. I believed many forum members will start posting soon. Keep a watch out on those, n good luck on your search
