When a player makes a combat check against a monster, he normally takes the maker tile and keeps it as a trophy. This is not the case for monsters with the Endless ability, or any monster whose marker is returned to the box or monster cup for any reason. Some rules on cards or markers may cause markers not to be taken as trophies, or cause markers to becomes trophies despite some other effect.
The toughness of a trophy is shown by the number of red droplets on the center bottom of the combat side of the marker. It often takes five or ten toughness in monster trophies to trigger an effect. In these cases, five toughness in monster trophies usually equals one gate trophy. You cannot "make change" in toughness; any uneven amount over what is spent is lost.
Spent trophies are returned to the monster cup.
Each three toughness in unspent monster trophies adds one when using the optional victory scoring rule.
A gate trophy is a gate marker earned by players for closing or sealing gates. When a player successfully closes a gate, they take the gate marker as a trophy and keep it with the rest of their tokens, cards, and other items. Gate trophies can be traded at certain locations in exchange for special items or events. For example - the Science Building allows investigators to exchange gate trophies for clue tokens.
Spent gate trophies are returned face down to the bottom of the pile of unused gate markers.
The Close the Gates victory condition requires the players to have at least as many unspent gate trophies as there are players; the trophy from the last gate closed counts.
The player with the most gate trophies after a victory is the First Citizen of Arkham.
Each unspent gate trophy adds one when using the optional victory scoring rule.
