Background: The UGT’s weekly sessions run for 10+ hours. Now anywhere from one to two hours gets eaten up by pre-game socializing and mid-game dinner, but generally speaking we start at 4pm Saturday afternoon and go till 12-2am Sunday morning. At the time of this encounter, we actually started at 2PM.
So, we were a party of 6 or 7 PCs plus a 3 or 4 cohorts, I was a recent addition to the group so my character was the lowest level at 9 and the highest were 11 or 12, I think. So, the DM was confident in our ability to handle rough challenges. Having tracked the BBEG to his cliffside fortress, we decided to climb down and walk in the front door, instead of our normal
motis operendi, which would have been to use
Rope Trick and
Feather Fall for a HALO style attack. Well, obviously the guards saw us coming before we were halfway down the cliff face. *Roll for an Initiative that would last for the next 8 weeks (+/- my memory is fuzzy, but if I err, it is likely on the conservative side). These sessions were running 2pm-3am, 4am, even 5am a couple of occasions. The running battle went along the path into the front doors, into the main complex, through a series of rooms and 'arenas' finally into the catacombs below for a head to head with BBEG 'LaProv' Yes, that's Vorpal backwards...
I don't recall what my XP haul was in the end, but I did go from upper 9th to 10th capped, leveled again the next week. (I was the only one getting xp for the dozens and dozens of ogres we fought.
