Machina Arcana 3.6 Rules Update
Deck Preparation and Management
Game Setup: Event Decks
When setting up the game and after selecting your scenario, the event decks (Explorer and Horror Event cards) need to be prepared in a new way:
- Select Core Event Cards: Take only the top cards from the shuffled Core events, equal to the number of event cards in the chosen scenario.
- Remove Excess: Remove the rest of the Core event cards from the game.
- Combine and Shuffle: Add the scenario event cards to their respective Core decks and shuffle them separately.
Adding Item Levels
When resolving add item level 2 or add item level 3 effects:
- Remove Cards: Remove half of the existing cards from all item type decks.
- Add New Items: Shuffle all the new item cards of the indicated level into their corresponding item type decks.
Increasing Monster Level
When monster threat increases on the last position (arrow pointing upwards):
- Shuffle the Monster Deck: Shuffle the current monster deck with destroyed monster cards.
- Remove Cards: Remove half of the cards from the deck.
- Add New Monsters: Shuffle the new monster cards of the corresponding level into the deck.

FAQ
- Recharge Station / Trade with any explorer adjacent to either a recharge station or a workbench, on any map tile
This includes the activated recharge station.
According to the inventory effect rules, you can resolve use inventory effect on an adjacent explorer instead, but not on the explorer you traded with if they aren’t adjacent to you. - Compatibility with other editions
