Go to Stonehenge, keep any valuable items, position
the pointer at "GOLD", "STRENGTH", "CONSTITUTION",
or "ENDURANCE" and press Fire. The druids will
continue the ceremony and your character will receive an extra
life without losing any items.
Alternatively, when entering Stonehenge and have to offer a magical
item to DANU, Click on "STRENGTH" for an extra life.
Repeat this as needed.
