Everburning Torch: Richardo treats Dark Cornerstone Chambers as if they were Lit.

Replace the text of “Cornerstones” with

The four rooms in the corners of the Zahndorf Crypt map are known as the Cornerstone Chambers and are always Dark. By default, Cornerstone Chambers have a background colour of #882200. They cannot be the subject of Power Actions, and may not contain Sigils, Glpyhs, or Sepulchres.

Each Cornerstone Chamber has a non-negative integer level of Haunt, which is by default 5 and can be no more than 5. A Cornerstone Chamber with 5 Haunt is considered to be Haunted, otherwise it is Weak. The Haunt of a Cornerstone Chamber is tracked in place of its name on the map though is not its name. (Cornerstone Chambers have no name and may only be specifically referred to by their grid position). Weak Cornerstone Chambers have a background color of #FF4400

The effects of Ricardo moving to a Cornerstone Chamber are as follows: he loses any Everburning Torches he is carrying. The Haunt of that Cornerstone Chamber is then reduced by Ricardo’s Energy, to a minimum of zero, and then Ricardo’s Energy is reduced by the same amount the Haunt was reduced by.

When the Crypt Settles, the Haunt of every Cornerstone Chamber which Richardo did not move into during journey that just occurred is increased by 1 (to a Maximum of 5).

In “Richardo’s Journey” add a new step after “Apply any effects of the features of that room, in the order that they are listed in the rule Features, to Richardo” that says “If the new room is a Cornerstone Chamber, apply the effects of Richardo moving there”
