📋 About This Mod
Challenge a series of powerful bosses in this unofficial Boss Rush Mode for Octopath Traveler 0.
Description
Octopath Traveler 0 - Boss Rush Mode adds a new boss rush challenge to the Monster Arena.
This mod lets you fight a continuous sequence of major story bosses, reworked into a single extended battle gauntlet. Bosses appear in their original event-driven forms as much as possible, with story progression flags removed and battle flow adjusted for a standalone challenge mode.
The rush is balanced for endgame parties. Recommended party level: Lv. 70+.

Compatibility notes
Extra Boss Mode and Boss Rush Mode can only be used together after merging them with Pak Merger. Both mods replace many of the same cooked database, NPC, text, and Monster Arena assets, so simply installing both mods will cause one to override parts of the other.
This mod edits game database, event, enemy, text, NPC, and Monster Arena-related cooked assets. It may conflict with other mods that modify the same areas, especially:
- Enemy stats
- EventList or boss event files
- Monster Arena/NPC placement
- Localized text database files
- Battle flow or boss encounter mods
If another mod uses a Pak with higher priority and modifies the same assets, one mod may override the other.
