I recently started DMing for my D&D group and I'm very reluctant to buy the DM screen. I fashioned my own out of five pieces of wood and I must say I'd rather not exchange it even if I do get around to buying the screen. My problem is that I do not have the charts included with it. I'm very new to DMing and I was wondering if anyone could suggest tables that I should have on hand during a session. Help is much appriciated.
