The original category of the revision was Killing Monsters. This still stands. However, if a party can otherwise defeat a monstrous encounter (subdual, capture, trapping, etc.) they will also earn the experience for defeating the beast. Of course if they do something stupid like letting it go, then no reward ... and the thing will likely have a Grudge. Grudge Monsters ... hell yea.
EP Per Encounter
With fewer encounters per level, how much should they be? The chart below covers the modification. Approximately 5 encounters per level, each encounter a bit tougher than suggested by the book, but still balanced to both the experience ration and the level of the characters. Mind you, there should always be encounters that are far tougher than listed as well as a few that are less intense.
For each encounter, roll 2d6. On a roll of 2, use an EP target of 50% of list, on a 3 75% of list. On an 11 125% of list, and 12 200% of list. For example, designing an adventure for a 4th level Party of 5 (where all the parents are dead):
2: 160 EP (easy peasy, but potentially tiring)
3: 200 EP (a bit less challenging)
4-10: 240 EP (standard fare)
11: 290 EP (ouch ... careful)
12: 500 EP (uh oh ... might need to run)
