Just played session 2 of my campaign tonight. I started up the game with my Doom Pool at 2D12, 2D10. Pretty hefty, right? That's after I had ended a scene in session 1 by spending 2D12 out of the pool. To be fair, my players were rolling a lot of 1s and I kept the doom pool to a minimum of dice at any given moment.
Tonight I made sure to spend dice judiciously to improve the challenges the heroes faced. I spent all sizes of dice out of the doom pool - D6 up through D12 (yes, I gave the players I hit with D12s a plot point for my evil). I managed to get the doom pool down to D12, D8 at one point but I still ended the session with 2D12, D10, 3D8.
Is this common? Should I be spending more from the pool?
