I am planning a campaign and I have everything situated except the battles and dungeons. What is the best way to determine what level the monsters should be so I don't destroy the players but they still have a challenge? How do you determine total Challenge rating for a fight?
Our DM recently gave us a wish for any item that costs 10,000gp or less. My girlfriend is looking for something that either 1. Mind control 2. Thought projection 3. Reads minds. Any suggestions?
