boosters.yml

boosters.yml determines how temporary EXP multipliers behave for a system.

Notifications and display

Path	Default	Description
`boosters.notifications.start`	`true`	Announce when a booster activates.
`boosters.notifications.end`	`true`	Announce when a booster expires.
`boosters.notifications.on-gain`	`false`	Send a message on every EXP gain while a booster is active.
`boosters.display.format`	`"&d{multiplier}x"`	How multipliers appear in messages.
`boosters.display.active`	`"&aActive"`	Label for active boosters.
`boosters.display.still-active`	`"{hours}h, {minutes}m and {seconds}s"`	Remaining time format.
`boosters.display.until`	`"&7until &e{end}"`	Timestamp label.
`boosters.notifications-interval`	`5`	Minutes between reminder messages.

Each booster rule lives under boosters.rules.<id>.

Field	Purpose
`enabled`	Toggle the rule.
`requires.players` / `permissions` / `group`	Restrict boosters to specific players, permission nodes, or custom groups.
`requires.level` / `prestige` / `playtime`	Minimum stats before the booster applies.
`requires.nearby`	Require a group of players within a radius.
`when.days` / `time.start` / `time.end` / `dates.start` / `dates.end`	Schedule boosters by weekday, clock time, or calendar date.
`when.duration`	Limit runtime in seconds (`0` = indefinite).
`events`	List of EXP events affected. Empty means all events.
`multiplier`	Base multiplier applied when the rule is active.
`stack.enabled`	Allow stacking with other boosters.
`stack.boosters`	Whitelist of booster IDs allowed to stack. Empty = no restriction.
`stack.multiplicative`	Multiply (`true`) or add (`false`) stacked multipliers.
`stack.max-multiplier`	Cap the stacked multiplier (`0` = unlimited).
`apply.commands` / `events` / `negative-exp`	Decide which EXP sources use the booster.

Stacking tip

Keep stack.multiplicative enabled for classic booster behaviour. Switch to additive stacking if you want precise control over the final multiplier.
