Magnus’s RPG empire on the portal.

-Yahaha!!!!Meat!!! Let the blood flow!!! Hack the living!!!! EAAAAAA!!!I turn around. I draw both swords and chop off the heads of the first two archmages I see. I don't turn around, but it seems like the undead have stormed through the city gates.

The battle is progressing slowly, all the monsters are dying. You need to break into the city and curse the city altar. Then the balance of power will shift in favor of the necromancers. But the portal is closed. What are your actions? An archmage's arrow hits you - 10 HP.
