The DMG rules that when facing several NPC encounters, doubling the number of foes adds 2 to the encounter level (page 37)
i have several questions about this:
1. is encounter level (EL) the synonym for challenge rating (CR)? if not, what does it signify?
2. does the cited rule only apply for enemy-npc encounters or for all battles against more than one foe of one "category". example: if one orc (without npc-levels) is cr 0.5, are two orcs cr 2.5 because of that rule?
3. how do you handle this xp-award question?
