Configurable XP Multiplier

XP GAIN MULTIPLIER

Borderlands 4 · Oak2 Python SDK · default 1. 5x

Multiplies character XP and specialization XP as you earn them. Kills, missions, and other normal awards all pick up the extra.

Default is 1. 5x (+50%). Change it any time from the Mods menu slider or the console.

Features

• [] Default 1. 5x XP on character + specialization tracks[/]

  []Slider in the SDK Mods menu: 0. 1x – 10. 0x[/]

  []Console: xp_mult to set, xp_mult_status to verify it is armed[/]

  []Host-side live write to OakPlayerState. ExperienceState (works in solo / listen-host)[/]

  []Re-arms cleanly after travel / possession so load-in XP is not treated as a giant award[/]

• [] Borderlands 4 (Windows PC)[/]

  []oak2-mod-manager v0. 3 (or newer) so the game has an sdk_mods folder[/]

  Setup guide: Oak2 Mod DB

  Install

  • [] Install the Oak2 Python SDK / mod manager first.[/]

    []Drop xp_gain_multiplier.sdkmod into:

    <BL4>\OakGame\Binaries\Win64\sdk_mods\[/]

    []Fully restart Borderlands 4 (quit to desktop).[/]

    []Enable XP Gain Multiplier from the Mods menu / mods console command.[/]

    []Load into the world, wait a couple of seconds, then play.[/]

  Usage

  • [] xp_mult — print current multiplier[/]

    []xp_mult 2 — set 2. 0x[/]

    []xp_mult_status — print armed state + live char/spec XP[/]

    After a kill you should see a console line like:

    top-up #1 track0: +1200 -> +1800 (1. 5x)

    If xp_mult_status still says calibrating, wait ~2 seconds in-world and run it again.

    Notes / limits

    • [] Host only. Guests in your lobby do not get the extra XP.[/]

      []Works on the live character, not by editing save files.[/]

      []Unofficial community mod. Not affiliated with Gearbox or 2K.[/]

      []Back up saves if you push the multiplier very high.[/]

      Combat-XP write path follows the same host-tick + ExperienceState approach used by community boosting tools (OnRep does not fire for the listen-host).
