LEVEL ADVANCEMENT WITHOUT XP
SESSION-BASED ADVANCEMENT
A good rate of session-based advancement is to have characters reach 2nd level after the first session of play, 3rd level after another session, and 4th level after two more sessions. Then spend two or three sessions for each subsequent level. This rate mirrors the standard rate of advancement, assuming sessions are about four hours long.
STORY-BASED ADVANCEMENT
When you let the story o f the campaign drive advancement, you award levels when adventurers accomplish significant goals in the campaign.

Might as well quote the book at this point and get everyone on the same page. Using Level Advancement Without XP and the Session-Based Advancement option means advancing every 2-3 sessions! each 4 hours, after level 4.
Despite what it says this in no way mirrors standard advance,ent. That is actually much faster than rewarding creature XP, unless you make the mistake I did and reward encounter difficulty
adjusted XP as a reward . The average pace of advancement based on adventuring days and creature XP for 3-6 creature encounters, and having all combat encounters, would be on average would be roughly 4-5 sessions per level. The only way to get 2-3 adventuring day sessions per level is for them all to be solo creature encounters or non-combat challenges.
Also note that in addition to not understanding their own adjust XP for encounter difficulty vs creature XP for adventuring days system (easy mistake IMO
), the designers pretty clearly expect a 4 hour session to be roughly an adventuring day's worth of encounters, combat or non. Given how often people complain about that clearly it's a problem for a fair number of folks.
