The text from offer:

*’’’Command’’’: “offer [Item]”
*’’’Steps added’’’: 2.
*’’’Other effects’’’: The Protagonist must announce his offering via a Blognomic post within 1 hour of taking the Action.  The Result of the Action may be added only by the Narrator.  The text in the Result affects the gamestate in whatever way it describes.  If the Result has any effect on the gamestate, the Protagonist’s Item Held is changed to Generic Receipt.
*’’’Criteria’’’: [Item] is the Protagonist’s current Item Held.  No Protagonist may make Offering more frequently than Often.

The statement from the Ruleset:

The Ruleset and Gamestate can only be changed when the Ruleset specifically permits their being changed.

What somehow happened:

“Therefore, the following listed items are the only effects of your (still very much appreciated) Offering:
1. Your (Elias IX’s) Item Held is changed to Awesomest Cheese.
2. Location “The Holy Furnace” is renamed “The Furnace of Benevolence”
3. Location “The Furnace of Benevolence” has Description set to “A furnace is set on the wall opposite the entrance of the tree. Next to the furnace is a sign reading, “Here were many Temptations resisted”.
4. The “Offering” Action is abolished—that is, deleted—from the Ruleset and all other existence.
