And that's it. What do you guys think?

Oh yes, this should probably be taken into account: Encounters 5 and 6 will be sequential.

[Curious]

PC classes have CR equal to level - 1.
NPC classes have CR equal to level - 2.

Find out the xp that each would give you when defeated.
Add them together.
Find the CR that gives the closest amount of XP to this result.
There you have it.

Huh. You know, when you put it that way, it's a lot simpler than it seemed. Thanks a lot! :-D
So, since I want the encounters to be somewhere in the range of Challenging, I guess I'd have to change them a bit:


Encounter 1: 5 bandits waiting to ambush the party

3 melee (Race/Class: Human Warrior 1; Init +1, Atk +4, AC 14, 9 HPs; Fort +3, Ref +1, Will +0; STR 14, DEX 12, CON 12, INT 10, WIS 10, CHA 10; Skills: Acrobatics +1, Climb +5, Stealth +1, Survival +1; Feats: Toughness, Weapon Focus [Heavy Mace]; Equipment: Dagger, Heavy Mace, Studded Leather Armor, 5 days' worth of trail rations)

2 ranged (Race/Class: Human Warrior 1; Init +1, Atk +4, AC 16, 6 HPs; Fort +3, Ref +3, Will +0; STR 10, DEX 16, CON 12, INT 10, WIS 10, CHA 10; Skills: Acrobatics +3, Climb +3, Stealth +3, Survival +1; Feats: Point Blank Shot, Precise Shot; Equipment: Dagger, Shortbow (20 arrows), Studded Leather Armor, 5 days' worth of trail rations)

Any comments on the encounters themselves? Are they alright? Too difficult? Too easy?
