I concur with Kharis in that Hamilton and Liz are as good as hosed if the others fail to save them.
As for Randell, Bill, and Lili, their best bet would be to run for the exit, and regroup on the surface to come up with a plan (assuming it's daylight out). With a 10 STR Automation going after three character's with 15 STR, 15 STR, and 20 STR, it would come down to them getting out of the tomb before they were out of END (again, if it's daylight outside). Maybe it would depend on how deep into the tomb the group were when they came across the Bandages? The GM would have to drop some clues on them as to Bandages' weaknesses (fire and sunlight in this case, they don't have a mystic with them to exploit the weakness to Dispel Magic).
