RPG Isekai Rondo Otogi: How to Beat Boss Momotaro

To beat Boss Momotaro in RPG Isekai Rondo Otogi, stack physical defense buffs on your frontline on turn one, maintain an attack debuff on Momotaro, and save high-cost burst attacks for his sub-30% enrage phase. Momotaro relies heavily on heavy physical strikes and single-target burst, making sustained mitigation and defensive guarding mandatory to survive his rotation.

Recommended Party Roles and Preparation

Momotaro tests your party's physical defenses and action economy. Equip armor that increases base physical defense and maximum HP rather than magic defense, as his skill pool consists almost entirely of physical martial techniques. Distribute recovery items across all active members so your dedicated healer does not waste turns handling minor HP top-offs.

Frontline Buffer / Tank: Casts physical shield buffs, maintains boss attack-down debuffs, and absorbs heavy single-target strikes.
Primary Damage Dealer: Focuses single-target offensive skills to cut through Momotaro’s defense stat rather than wasting resources on area attacks.
Support / Healer: Casts group recovery, cleanses ailments, and manages party MP and SP replenishment.
Flex / Item Specialist: Uses consumables to sustain team health and resources between spell casts, supplementing damage during safe turns.

Momotaro Battle Phases and Strategy

Momotaro shifts his attack patterns across three distinct health thresholds. Adjust your actions according to his current phase:

Phase	Momotaro's Pattern	Priority Actions
Opening (100%–70% HP)	High-speed single strikes; buffs his own physical attack	Apply Attack-Down debuffs immediately; cast party physical defense shields
Mid-Fight (70%–30% HP)	Alternates heavy cleaves and charged, telegraphed techniques	Put squishy units in Guard stance on tell turns; restore party HP to full
Enrage (Sub-30% HP)	Increased critical hit rate and rapid multi-hit strikes	Drop defensive setup; expend all remaining SP and burst skills to finish the fight

Countering Momotaro's Rotation

Suppression on Turn One: Apply a physical attack debuff on Momotaro immediately. If your party composition lacks an attack-lowering skill, raise party-wide physical barriers before he attacks to prevent instant knockouts from early critical hits.
Defend Charged Tells: When Momotaro enters a charged stance or signals a heavy skill, switch vulnerable units to the Guard stance for that turn. Guarding cuts incoming damage and reduces critical spike risk, allowing your frontline to absorb the hit safely.
Exploit Cooldown Windows: Momotaro's threat level temporarily drops for one to two turns after he executes a major power move. Use this window to recast falling buffs and unleash high-potency single-target offensive skills.
Preempt Buff Expirations: Recast defense shields and attack debuffs a turn before they expire. Allowing mitigation to lapse leaves your party exposed to unmitigated strikes.

Executing the Sub-30% Enrage Phase

When Momotaro drops below roughly 30% HP, prolonged defensive attrition becomes unsustainable due to his increased critical rate and multi-hit frequency. Once he enters this range, abandon defensive recasting, maintain only essential healing, and spend your accumulated gauge moves, high-cost SP skills, and offensive consumable items to eliminate his remaining health before his accelerated attack cadence overwhelms your squad.
