Henry said:My answer is a combo of #2 and #3. Mostly I stay within +2 or -2 EL of the group's level, but last week I faced up bunch of 5th level characters with a Beholder. Before you think me mad, there were 10 characters in the group at the time, including 4 NPC's of higher level than the PC's, and one thing about EL's that don't scale well is when there are FAR more characters than the opposition.
