Module: Carrion Crown Adventure Path
Force Green's "Core 4" (Pyia, Blue, Blood, and Drizmar), along with their distant cousin Goldy, had the servants buy 2 scry scrolls to scry on the frost giant lich king of Bloodstone so they could then teleport directly into his chambers. They scried on the room, saw the enemy forces, and sent the servants for 5 more scrolls (arcane lock for the magically sealed door behind the enemies with the phylactery vault inside).
Once the group teleported in, they focused on stealing the frost giant lich’s belt. Once again, the team was almost defeated. When the rest of the group was all unconscious and/or bleeding to death, Pylia teleported them away for a retreat [for 5 rounds so they could heal up and come back]...
They returned for a final battle. This time everyone went down except for Blue; thus the epic combat ended up with the satyr paladin standing against the lone remaining enemy - a death knight! Blue won and secured success for the team, reviving the others. The team gained a fire elemental statue (from petrification).
In the end they got the bag with 8 phylacteries, destroyed the 4 with souls in them, and decided to keep the other 4 phylacteries as leverage to try to control whatever liches remained in the city above. The group decided to rest in the lich lair/vault.
