S-tier party healer with no equivalent substitute. Booshu restores 3 HP to all allies per Counter 5 activation — the only Pet with a full-party heal effect. In a 3-companion party, each Booshu activation recovers 9 total HP across the team. Against sustained boss fights where your party loses 5–8 HP per exchange, Booshu's activations extend the fight by preventing attrition defeats that would otherwise end runs.

Counter 5 is slow for a combat role, but Booshu's healing doesn't need to keep pace with damage — it needs to prevent cumulative HP loss from compounding to fatal levels. One Booshu activation every 5 turns restoring 9 total HP is enough to offset the average damage taken by most late-act fight sequences.

3 Attack contributes secondary damage alongside the healing. Booshu isn't a pure support unit — she deals damage AND heals. The healing is what makes her S-tier; the damage is a bonus that the heal role doesn't typically provide.

Any run where HP conservation matters across multiple fights within a chapter benefits from Booshu. Companions like Lil Berry (gains +2 Attack when healed) and Firefist (gains Spice from HP loss, which Booshu's heals then reset for more Spice cycles) gain additional scaling directly from Booshu's heal activations.

Back row — HP 4 is low and Booshu dying removes the party's only sustained healing. Protect her behind front-row tanks and mid-row attackers. Her Counter 5 fires from any row, so back-row safety is always preferred.

HP investment on Booshu directly increases her healing lifespan. At 4 HP, she falls to a single strong enemy attack. At 8 HP, she survives 2–3 hits. A +4 HP charm on Booshu (4 → 8 HP) might represent 2–4 additional Booshu activations per run — translating to 18–36 additional total HP healed across the party.

Counter-reduction on Booshu changes the math significantly. Counter 4 Booshu heals 25% more frequently than Counter 5 — in a 10-turn fight, that's 2 activations vs. 3 activations, an extra 9 HP restored across the party.

Lil Berry + Booshu heal scaling. Lil Berry gains +2 permanent Attack each time she's healed. Each Booshu activation that heals Lil Berry gives her +2 permanent Attack. Over 3 Booshu activations, Lil Berry gains +6 Attack from Booshu alone — plus Big Berry row-clear healing stacks on top.

Firefist + Booshu Spice cycling. Firefist gains Spice equal to HP lost. Booshu restores HP. If Firefist takes damage, gains Spice, attacks for high damage, then Booshu restores the HP — Firefist can gain Spice again from the next damage cycle without dying. Booshu enables Firefist to sustain the damage-intake Spice loop across a full boss fight.

Lupa + Booshu Counter management. Lupa reduces all ally Counters by 1 per turn. With Lupa active: Booshu's effective Counter drops from 5 to 4. Counter 4 Booshu activates 25% more frequently from Lupa's passive alone, without spending any charm slots on Counter reduction.

• Lil Berry — each Booshu heal gives Lil Berry +2 permanent Attack; Booshu becomes a scaling engine for Lil Berry through repeated healing
• Firefist — Booshu restores HP that Firefist lost (gaining Spice); allows Firefist to enter more damage-absorption cycles without dying
• HP-up charms on Booshu — highest-return investment given her 4 HP floor; each +HP is more heals per fight
• Counter-reduction charms — Counter 5 → Counter 4 adds one more activation per 10-turn fight, equivalent to 9 more total HP healed
• Lupa — Lupa's passive Counter -1 effectively makes Booshu Counter 4, increasing heal frequency without charm cost
