How this page is made
Game files (client 2026.10.21 (Steam build 26077854, 2026-10-21)): the lines the game shows when a boss casts or uses a skill, gets a buff, starts or dies (NpcBehaviorCase → NpcTalk: “Guide” = the Shugo guide's hint in the Exploration run, “Boss” = the boss's own shout), the skill's name, cast time, cooldown and range (Skill), the buffs and debuffs it applies with the game's text (SkillEffect → SkillAbnormal), the Frenzy timer (NpcData.BossBerserkInvokeTime) and the stagger. Many boss skills are only called “Attack” in the files; those cards are named by their effect or by the action they ask for. HP thresholds are not in the client.
The action label on each card is our reading of the guide's line, by its words: the first that matches of “Big alone, small together”, “Stagger it”, “Stop attacking”, “Break free”, “Climb up”, “Jump”, “Take cover”, “Block it”, “Lure the boss”, “Colours”, “Kill it first”, “Stack up”, “Spread out”, “Find the gap”, “Get in”, “Move out”, “Burn it down”. The line itself is the game's.
