Warband Upgrade Ultimate – SFO Compatibility Patch

This is a dedicated compatibility patch for Warband Upgrade Ultimate and SFO: Grimhammer III.

It adds safe and lore-friendly SFO unit support to the Warband Upgrade system, adapting upgrade paths and costs to SFO’s slower campaign economy while preserving faction restrictions and the logic of the original mod.

---

• Makes Warband Upgrades Ultimate work properly with SFO / Grimhammer III;
• Integrates SFO units into the Warband Upgrade system where the upgrade path is safe and logical;
• Adjusts upgrade costs to better match SFO’s slower and more demanding campaign economy;
• Preserves faction restrictions, so units should not appear in armies where they do not belong;
• Keeps upgrade chains lore-friendly: units are only connected when the progression makes sense;
• Supports the Warband Upgrade UI, so compatible upgrade groups should appear in the campaign interface;
• Avoids forced or strange upgrade paths for special, summoned, bodyguard or unique units.

Required:
• Warband Upgrade Ultimate;

• Warband Upgrade Ultimate
• SFO: Grimhammer III

Keep this patch above Warband Upgrade Ultimate and SFO so its compatibility changes can properly override both.

---

This is a compatibility patch only. It does not redesign the Warband Upgrade system and does not try to force every SFO unit into an upgrade chain.

The patch focuses on safe SFO integration: logical upgrade paths, faction restrictions, upgrade costs, campaign UI support and clean progression between related units.

The original mod is safe to add or remove mid-campaign and is fully functional in co-op. This patch is designed to follow the same lightweight compatibility approach, but after major updates to Warband Upgrade Ultimate, SFO or the game, a new campaign is still recommended for the cleanest result.

Do not use multiple SFO compatibility patches for Warband Upgrade Ultimate at the same time unless they are explicitly designed to work together.

---

Potential conflicts may happen with mods that change the same Warband Upgrade chains, SFO units, faction restrictions, upgrade costs, UI integration or unit progression logic.

This patch is designed specifically for Warband Upgrade Ultimate and SFO: Grimhammer III. It is not intended for other major overhauls such as Radious.
