Requirements

For Bannerlord 1.5.2 Beta single-player. Requires Harmony 2.4.2.248 and the compatible RBM 4.3.5 build named on the download page. If you use War Sails support, keep the original RBM_WS module installed too.

This download is a patch. RBM remains a separate required download. Do not assume that a newer RBM build is supported simply because its version looks similar.

Installation and activation

Close Bannerlord. Install Harmony and the required RBM build, then install the WPS patch through Vortex and deploy it.
For a manual installation, place the complete WPS_RBM152Fix folder inside Modules.
Keep the official modules enabled and order the mod requirements as Harmony, RBM, optional RBM_WS, then WPS RBM Compatibility Patch.
Fully restart Bannerlord after changing RBM or the patch. Check the main menu for the green WPS activation message.

Nexus Mods ↗

Choose ranged timing

From the main menu, open RBM Configuration and find Ranged pull, reload, and aim timing. Vanilla uses the original game’s timing; Realistic and Semi-realistic keep RBM’s timing. The choice takes effect for the next mission.

RBM’s combat, AI, posture, tournament, and other settings remain available, including its War Sails options when installed. The patch supports new and existing Story and Sandbox campaigns on its stated game version.

If the patch does not activate

A red warning means the installed RBM build is not supported. Check the required RBM download and load order, then fully restart the game. Do not substitute an unrelated RBM build to clear the warning.

When requesting help, include your game branch, RBM and WPS versions, download source, load order, and which RBM components are enabled.

Nexus Mods ↗

Removing the patch

The patch does not replace RBM’s original files. Remove the WPS patch and return to a Bannerlord version supported by your installed RBM release before playing without it.
