When you get the Zombie disease it takes you like 45 seconds to turn into a zombie.
Get the disease, walkthrough the portal room, go through your portal, hit the zombie explode button, res and go do what you need to do.
You’re being really over dramatic. You’re a Paladin. Use your bubble when you run through the portal room or use lightfoot potions, invis potions. Get creative.
Unplayable is a total exaggeration.
