In the Lords of Xulima Delux Edition, how do I get into the Tower of Scorsery?

How do I survive the poisonous Mushrooms. And how do I enter Tower of Wizardry; I;ve killed the crows.

You need to move around the mushrooms and avoid combat with them. It can be difficult. You have to go the region of Sorrentia and into the Golden Forest where you have to avoid stepping on the flowers to progress. There you`ll find a dude you need to talk to.

To get past the mushrooms, hover over their image to see their field of control. Just make sure you stay out of it. (you can come back later when you're stronger to slaughter them)

Yep and one should do that to farm XP.
