Added

• /f power buy <amount> subcommand: opt-in feature (disabled by default) allowing players to purchase personal power with money via Vault. Configurable cost per point and per-purchase cap (factions.power.buy.*).
• New config.yml keys: factions.power.gain-on-kill.enabled, factions.power.gain-on-kill.amount, factions.power.buy.enabled, factions.power.buy.cost-per-point, factions.power.buy.max-per-purchase.
• New messages.yml keys: power.lost-on-death, power.kill-gained, power.buy-success, power.buy-disabled, power.buy-no-vault, power.buy-invalid-amount, power.buy-already-max, power.buy-insufficient-funds.

Changed

Teams API updated

The TeamsAPI integration now has access to faction claims and faction power, making it possible to connect other plugins to it and making a more unique Factions experience per server.

• TeamsAPI ClaimService adapter: claim and unclaim individual chunks, bulk-unclaim by team, query claims by chunk or team, check whether a chunk is claimed or owned by a specific team, and compute max claim allowance from total power.
• TeamsAPI PowerService adapter: get and set individual player power (clamped to configured max), query total and max power for a team.
• FactionTeamClaim value type bridging internal BoardEntry data to the TeamsAPI TeamClaim contract.
• Updated TeamsAPI dependency from 1.3.0 to 1.4.0.

Power engine improved

To create a gameplay flow around power we have decided to make it kill based by default with an opt-in power buy feature (/f power buy <amount>).

• Power loss on death: players lose configurable power (factions.power.loss-on-death, default 4.0) when killed; respects the server-start grace period and skips safezone territory.
• Power gain on kill: killing an enemy player grants the killer configurable power (factions.power.gain-on-kill.amount, default 2.0); opt-out via factions.power.gain-on-kill.enabled.

Fixed

• Plugin crashed on startup with NoClassDefFoundError for TeamsAPI classes when TeamsAPI was absent or not yet loaded. Removed load: STARTUP so the plugin loads in the default POSTWORLD phase (respecting softdepend order), and changed BootstrapContext adapter fields to Object to prevent eager JVM resolution of TeamsAPI interface types.
