I'm currently running a D&D 3.5 campaign in the Eberron campaign setting, and the characters range in level from 11 to 13. I've noticed recently that combat has become slow and tedious. Multiple attacks, spell resistance, psionic power points...it takes an hour to get through a single encounter these days. I was wondering if anyone had any suggestions for how I could speed up these combats. And before anyone says it, switching game systems is not currently an option.
