As a mage:
Running around trailing a wall of fire. Dual purpose of not getting hit by hellspikes and killing of dwarves that are tracking you.
Loading up on a damage shield and then spamming elemental bolts, running around to use a restoration potion, rince & repeat till Josephina runs.
As a warrior:
Barge in, toss around a lot of whirlwind attacks, keep a finger near the restoration spell hotkey, restoration potion hotkey, stamina potion hotkey.
Smack up Josephina ignoring the hellspikes.
As a survivor:
Toss in scorpion traps (and remember there is no such thing as overkill).
