Multiplayer

Multiplayer allows you to play with up to 3 other players in the same run, allowing cooperation between each other when fighting through the acts.

Starting runs with other players adds many changes to the game, many of which do not exist when playing alone.

## Starting Multiplayer

To start a multiplayer run you must start a new adventure from the main menu to enter a lobby. Other players can be invited the lobby that you are playing in, or you can join a lobby that other players are already in.

Enabling matchmaking will automatically attempt to place you in the most viable lobby, or lets other players automatically join yours.

Alternatively each lobby has a code. Your lobby's code can be copied by pressing a button next to the Squad ID, which then lets you sent it to others. If you've received another player's code, a flag button in the top-right of the screen just below your name and level can be clicked, which opens a box letting you paste the code.

## Multiplayer Changes

### Enemies

Enemies gain extra  Health? and  Shields?/ Armor? based on how many players there are. Total increases to 300%, 500% and 700% for 2, 3 and 4 players, respectively. (These numbers increase to 500%, 900% and 1300% under unknown circumstances, but has be seen on Reincarnation 8.)

If a player has left the game, the enemy health will be adjusted at the start of the next stage.

### Reviving

When a player's Health reaches 0, they are knocked down for a certain amount of time and must be revived. Downed players are capable of crawling along the ground, but cannot perform any other action.

Other players can revive downed players by approaching and holding the Use key (default key is F) which will allow them to keep fighting after a successful revive, however players that are revived this way have very low Health. Players that are reviving a downed player can be interrupted or killed, halting the revive attempt. Additionally, players doing the revive cannot perform other actions, but an already started reloading will not be cancelled.

Reviving using  Soul Essence? can still be done like in solo, fully restoring Health and Shields/Armor, but can only be used once.

If a downed player is not revived by another player and runs out of time, they will be fully killed and cannot be revived. Instead they will spectate other players. Dead players can be brought back by paying a large amount of  Copper? at a Peddler. Players are automatically brought back when leaving a boss stage.

### Down Penalty

Each time a player is knocked down they receive a stackable penalty to the time they have to get revived. Players start with a default of 16 seconds to be revived, with each stack of Down Penalty dropping the duration by 2 seconds, down to a minimum of 4 seconds.

### Pinging

Players can ping things to notify other players about them (default key is V). Such things that can be pinged include chests and vaults.

### Items

Each player gets their own set of items dropped by enemies, given by chests or sold by Peddlers. This includes  Copper?,  Soul Essence?, weapons, occult scrolls,  Goblets and  Bun? drops. Players will not see what is dropped for other players.

Weapons and occult scrolls can be shared among players, either by dropping them after picking them up (Holding the  Weapon Skill? key, default is Right-Click) or by using the Ping key.

### Communication

Players can use in-game voice chat (default key is T holding down) or text chat (default key is Enter) to send messages. By holding down Ping key, it is also possible to send one of 4 emoticons currently selected.

### Other

* The game will not pause when opening any sub screen. This is kept even if there is only one player left in the team.
* The game will announce when a player enters vault or interacts with any  Goblet.
* Players without certain DLCs can still play with those having DLCs. In this case, they don't have DLC weapons spawn, but can use DLC weapons if teammates share them.

## Multiplayer Advantage

When playing with others, certain things are made easier.

* With player revival, each player is not limited to 2 deaths per run, greatly extending how long runs can last.
* Sharing can be done if a player finds a weapon or occult scroll that they won't use, but another player will.
* Multiple players can hold and fire different elemental weapons, making elemental fusion effects far more likely.
* Depending on the hero chosen, certain players can stick to certain roles, such as controlling enemies, clearing groups, taking damage or focusing on powerful enemies.

## Multiplayer Disadvantages

There are some downsides to playing with other players.

* Enemies have larger amounts of Health and Shields/Armor, even if players are dead. This can make it far harder for the remaining players to proceed.
* Dead players that are brought back do not receive any of the items that they missed while dead. This can result in weaker players overall that can lead to future deaths.
* Players who rush ahead into rooms before others are ready can often get themselves knocked down by overwhelming odds, forcing everyone else to rush in and revive them, or else lose a player.
* Some attacks are more intense the more players there are, which can lead to some players getting hit by attacks intended for someone else.
* Miasma? damage increases based on its usual damage and the player count. This makes it kill enemies slower due to the additional enemy Health multiplier, which is a bigger number.
