I'm playing "A Thief in the Night" scenario in Heroes 3 which is part of a Campaign. The scenario description asks me to acquire the Vial of Lifeblood artifact to win the scenario. I have done this, but nothing is happening. The description does not say to do anything else so... im stuck. Any ideas?
You actually need to create the Elixir of Life by giving the Vial of Lifeblood to Gelu, who should also have the Ring of Life and Ring of Vitality from the previous two missions. Once he has all three, you can merge them into the Elixir and win.
