RMDAVIS I find RPG Patsy to be nearly indispensible as a playing aid in my game as a D&D version 3.5 player. It handles all of the mundane and tedious stuff that would take hours of study and tinkering to do effortlessly. It has, however, been "broken" by the new Mac OS "Leopard" (OS 10.5). It will not load without crashing. If you're still using Tiger as your Mac OS, I highly recommend this for any 3.5 D&D game. Beware if you're using Leopard- at least until they come out with fixes.
