List of Treasures/Power-Ups
The One Item That Affects All Players
The Dark Moon Crystal - The most important power-up/item of the game is the Dark Moon crystal. At the start of the game, one of the players on the Ghost (Townie) side who does not have a role (aka a regular townie) will be assigned the Dark Moon crystal. For any side to win this game, they must be in possession of the crystal. For instance, if the mafia side has achieved a tie but they do not have the Crystal in their possession then the game goes on until they do.
If Luigi or Gooigi acquires the crystal then the game enters a Sudden Death period for the next day. Luigi or Gooigi (whichever one has current control of the Dark Moon) must be eliminated by the end of that day/night cycle. If not, then that player will escape the mansion with the Dark Moon to give the crystal to E. Gadd causing ight to shine forth and destroy the mansion eliminating the rest of the players and Luigi or Gooigi would win. It will only be announced if Luigi or Gooigi acquire the Dark Moon crystal. If, during the game, another townie or a a Mafia member ends up with the Dark Moon crystal then it will not be announced.
The Dark Moon crystal is the only item that can be swapped among players. If the player with the Dark Moon is voted out then it will randomly go into the possession of one of the players who were responsible for that vote-out. When a player gains possession of the Dark Moon, whatever Treasure or Power-Up they had before becomes inactive and the Dark Moon then becomes the treasure associated with them which they have until their demise or win. However, if they are eliminated then the power-up/treasure they had before will become active again. This is a key point since the Suction Shot power-up will allow a Killer to get treasure from deceased players. Luigi and Gooigi are the only players who can have or hold on to multiple power-ups/treasures and use them.
The rest of the items below are mainly for the benefit of the Ghost Busters Luigi and Gooigi as they will be the only ones who can use the Power-ups. (Although not every Treasure is of benefit to them.) That said, there are some treasures tied to specific roles. Knowing what roles have which treasures could be of benefit to the players and perhaps players would want to eliminate a specific player to ensure the killers are unable to acquire a certain power-up.
Role Specific Items/Power-ups
Virtual Boo (The Brain) - If The Brain is eliminated by a killer then all of the detectives previous investigations and results up to the time of their elimination will be given to the killer that eliminated them. If The Brain has been stacking investigations then all those stacked investigations are given to the killer who eliminates The Brain. The same rules for the The Brain’s role would apply to the killer’s use of investigations with one exception. They cannot stack vote investigations unless they have the Strobulb. If they get the Virtual Boo and The Brain had stacked up some of their investigations but the killer does not possess the Strobulb then they must use up all those saved investigations on the day they get the Virtual Boo or lose the opportunity to use them.
Golden Bone (Vincent Van Gore) - If Vincent is eliminated by a killer then that killer will be given a Golden Bone which allows them to automatically survive a hit or vote, whichever life-threatening emergency happens first. It is a one-time automatic use and cannot be replenished after being used.
Water Elemental Medal (Grouchy Possessor) - If the Possessor is eliminated by a killer then that killer will gain the Fire Elemental Medal allowing them to wash away a player’s vote and write in a new one for them. If the Possessor had been stacking their ability then the killer would inherit those saved vote changes. The same rules for the Grouchy Possessor’s role would apply to the killer’s use of vote changes with one exception. They cannot stack vote changes unless they have the Strobulb. If they get the Water Elemental Medal and the Grouchy Possessor had stacked up some of their manipulations but the killer does not possess the Strobulb then they must use up all those saved manipulations on the day they get the Medal or lose the opportunity to use them.
Hyper Strobulb (Hellen Gravely) – If Hellen is eliminated by a killer then that killer will now control the tiebreak in place of Hellen. By having the Hyper Strobulb, it is like they can stun every player for a moment to then make their choice of elimination. The same tiebreak rules apply to the killer who may get this ability.
Super Poltergust (Ug/King Boo) - Both Ug (the townie vigilante) and King Boo have the same power-up available and assigned to them. If a killer eliminates either Ug or King Boo then they will gain the Super Poltergust power. If a killer eliminates both Ug and King Boo then they would get the Super Poltergust each time. The Super Poltergust is an extra hit that the killer can make. A killer can hold on to the Super Poltergust ability and save it for use whenever they’d like to activate it but once it is used then it is gone forever. The reason it is the Super Poltergust is because the hit can even be done during the day period to eliminate someone. However, the killer will not gain that player's treasure/power-up if they eliminate them during the Day period with Super Poltergust. The Super Poltergust can even nullify Vincent Van Gore's (townie doctor's) protection and still eliminate its target. It is the only item/ability that can do this.
5 Gold Bars (Kung Boo) - If a killer eliminates Kung Boo then the player gets Kung Boo’s treasure of 5 Gold Bars. That amount of money will automatically allow the killer to buy the Gem Finder which they can use to find out which player currently has possession of the Dark Moon crystal. (I could have just made the item the Gem Finder but then why would the Boo Mafia have it and not use it? So, we’ll just jump through extra story steps to make it all seem sort of logical). The killer with the Gem Finder can then use it once each day and night cycle to see who has the crystal at the time they use that ability.
Dark Light Device (Boogie Woogie) - If a killer eliminates Boogie Woogie then that Ghost Buster will get the Dark Light Device. It allows that killer to make an investigation of any player (dead or alive) of their choosing in a Day and Night cycle to learn what item/power-up that player has. This could be considered more powerful than the Virtual Boo since King Boo cannot hide what type of power-up is assigned to them. A killer cannot save up or stack item these Dark Light investigations unless that killer has the Strobulb ability.
Key (Boo B. Trap) - If a killer eliminates Boo B. Trap then they will get a Key. The killer that obtains it will be able to escape the day vote and any actions preformed against them during the day except investigations. It as though they entered the next room of the game and out of the room the rest of the players are gathered in during the day. The killer who has the Key can only use it once and then it is gone for the rest of the game. As well, they would still be susceptible to night actions after the Day period is over.
Poltergust 5000 (Luigi) - If Gooigi successfully eliminates Luigi then Gooigi gains the Poltergust 5000. Basically, it just means that Gooigi will inherit all of the abilities the Luigi player has gained up until their death. Of course, the biggest gain for Gooigi eliminating Luigi is likely being able to now make a hit every night.
Poltergust G-00 (Gooigi) - If Luigi successfully eliminates Gooigi then Luigi gains the Poltergust G-00. Basically, it just means that Luigi will inherit all of the abilities the Gooigi player has gained up until their death. Of course, the biggest gain for Luigi eliminating Gooigi is likely being able to now make a hit every night.
Evershade Ghosts (Regular Townies) Specific Items/Power-ups
Fire Elemental Medal - With this ability, a Luigi can nullify (burn away) someone's vote for the day. However, they do not get to change the vote. They just keep the targeted player from being able to vote. The player who is targeted will not know their vote doesn't count although it may be figured out if players are trying to achieve a Majority Vote and it doesn’t happen. If the player who is targeted with the Fire Medal has a role then they can still perform the actions of that role. It is only their vote which is lost for the day. The killer with this ability can only use it once per Day cycle unless they have the Strobulb in order to stack up and save this ability to unleash multiple nullifications all at once at a future time. As well, it has to be used before the Day Vote is locked in. It cannot be used to erase a vote after the Day Vote has been locked in.
Ice Elemental Medal - With this ability, a killer can nullify someone's role for the day. The player who is targeted will be informed that they've been "frozen" and cannot perform their action that day. However, this player can still vote in the day thread. It is only their role ability that has been frozen. If the current Godfather is frozen then they cannot send out the squad on a recon mission nor make a hit. The killer with this ability can only use it once per Day and Night cycle unless they have the Strobulb in order to stack up and save this ability to multiple nullifications at once at a future time. There are times when this ability may have no effect. For instance, if the townie detective sent in and received their investigation for that Day and Night cycle and then is targeted by the Ice Medal four hours later then it is too late to stop that investigation and the attack has no effect. It does not carry over to the next day.
Strobulb - If a killer gains this ability then that killer can start saving and stacking up abilities that allow stacking and saving. Items/Power-Ups that can be stacked are: Missiles, Super Missiles, Ice Beam, Visor Scans, and Grapple Beam Shots. Without the Strobulb, a Luigi or Gooigi with any of those items/power-ups can only use them once each day and night cycle for however long they may have them. If they do not use an ability that day such as an investigation then that killer misses out on the opportunity for it to be used and it does not carry over to the next day's opportunity. The normal rules and requirements for saving and stacking an ability apply with the Stobulb power-up.
Suction Shot - With this ability, a killer can steal the power-up/treasure from any player whether dead or alive. The player with this ability can only use it once each night cycle unless they have the Stobulb which would allow them to stack up and save this ability and then gather more power-ups at once at a future time. Note: it is possible for a player to have no item/power-up after being eliminated from the game. For instance, if they were in possession of the Dark Moon crystal at the start of the game and were eliminated, someone else will then have the Dark Moon and therefore there would be no other item/power-up on that eliminated player for the killer to steal if targeted with the Suction Shot.
Polterpup - If a killer finds this ghost then instead of gaining an ability they will lose an ability chosen at random. They cannot gain this ability back unless they have the Suction Shot ability so the killer affected by Polterpup better hope that is not the power-up that gets stolen from them. The power-up that gets stolen will now be the power-up that is attached to the townie that had the Polterpup. In the extremely rare case the killer was in possession of the Dark Moon crystal when they made the hit on the townie with Polterpup and the Dark Moon crystal is the item that gets selected to be taken away then the Dark Moon is removed from the game and the game continues on as a normal game without the Dark Moon being needed for a side to claim victory. However, if Luigi or Gooigi has possession of the Suction Shot item and uses it to take the Dark Moon crystal from this eliminated player then the crystal is back in play with that killer having a chance to win with it and putting the game into a sudden death scenario.
Thieving Slinker - If the killer finds the Thieving Slinker then the Slinker will steal their Poltergust thus causing that killer to lose all gathered abilities up to that point and have to start over in gathering power-ups and treasures. Unlike the Polterpup, the player with the Thieving Slinker does not have all those abilities then assigned to them as their new item. Thus, a killer could not regain what was lost if they acquired the Suction Shot later and then targeted the townie who has the Slinker, for example. The Slinker steals the Poltergust and is never seen from again….
