Okay, so my party couldn't handle Brazzemal. Vercinabex killed the spellcaster with a prismatic spray, which also caused insanity in the bard.
The Blackguard, Ranger, and Cleric couldn't handle it when Brazzemal made his appearance, wherein the Blackguard was killed with a series of melee attacks and his breath weapon, while the Ranger and cleric where near dead. So, they had the bright idea to planeshift to the Astral Plane, sleep and heal, and then try shift back and continue the fight. They just forgot about the part where you appear 5-500 miles from your target.
So now, Brazzemal escapes with the phylactery (Which he took from Gazzelfek before combat). What happens? I looked throughout the magazine and it always assumes that the PC's got the phylactery and got away. Is there some way to continue the adventure, even though Dragotha has hs phylactery and probably hid it? Because Idon't want to end the adventure here.. .
Any suggestions are happily taken.
