Beast of Reincarnation Builds — Best Builds for Emma & Koo
The best Beast of Reincarnation builds: Emma's weapons and armor, Koo's Charms, Spirit Stones, and a full Poison build — plus the best early attributes and skills.
Beast of Reincarnation Builds — Best Builds for Emma & Koo
Beast of Reincarnation gives you two characters with two completely different equipment systems — Emma builds around weapons and armor, Koo around magical Charms. Understanding how their setups work separately, then how they combine, is the difference between a smooth run and getting stuck on a Nushi. This guide covers the best early build for both, the Poison build (the strongest damage-over-time playstyle), and the upgrades worth prioritizing.
Here's what you'll learn:
- How Emma's and Koo's equipment systems differ
- The best early attributes and skill priorities
- A full Poison build — weapons, ranged, Spirit Stones and skills
- Other viable playstyles (stealth, ranged, burst)
- Where to farm Spirit Stones and Charms
- Whether respec is possible
Two Characters, Two Build Systems
Before any build talk: Emma and Koo use entirely different gear.
- Emma builds around weapons and armor — the classic action-game loadout. Her build direction is melee-focused: weapon choice, armor stats, and stamina management.
- Koo equips Charms — magical accessories that are his primary equipment. Charms boost attack, defense, critical rate, survivability, and can add elemental effects or special combat bonuses.
A complete "build" in Beast of Reincarnation is really Emma's loadout + Koo's Charms + shared Spirit Stones + both skill trees working together. Treat them as one unit, not two separate characters.
Because Koo's equipment is invisible (no armor pieces to compare), it's easy to forget to upgrade it. Charms that raise critical rate or add elemental damage change Koo's output dramatically — always check for new Charms when you're back at the Walker.
Best Early Attributes & Skills
The early game punishes glass-cannon builds: limited healing, stamina-heavy combat, and dangerous encounters before stronger equipment unlocks. Priorities:
- Survival first — maximum health and stamina skills for Emma; survivability Charms for Koo
- Stamina management — the combat system has several speeds, and running out of stamina mid-combo is how most deaths happen
- Exploration QoL — anything that speeds up travel or reduces fall damage pays for itself across the huge zones
- Then offensive upgrades once your healing (Stimpack) progression is online
The opening hours are noticeably harder if you spread points across offense and defense evenly. Pick a direction (survivability now, damage later) and commit.
Skill Trees: Emma & Koo Together
Both characters have their own skill tree, and a build lives in the intersection of the two:
- Emma's tree covers melee combat — light/heavy attacks, dodges, stamina economy, and weapon-adjacent passives. This is where your survival-first points (max health, stamina) go early.
- Koo's tree covers ranged play — ammo efficiency, skill upgrades, and Charm synergies. Early Koo points in ammo and skill efficiency keep him relevant while Emma carries the early game.
Decide your playstyle first (poison, stealth, ranged, burst), then spend both trees toward it. A poison build wants Emma's poison/status passives and Koo's elemental Charm scaling — spending one tree without the other gives you a half-build.
Poison Build: The Full Setup
Here's the complete poison loadout, from gear to playstyle:
- Emma's weapon: Hunter's Sword (27 attack, Envenomed — poison buildup +5, 5-second effect, refreshed by consecutive hits)
- Ranged backup: Poison Arrows and Poison Bolts for safe application and kiting
- Koo's Charms: prioritize elemental/poison-related effects and critical rate — they multiply the DoT's value
- Spirit Stones: socket poison application and damage-boosting stones where available
- Playstyle: keep Poison active on the boss at all times — refresh before the 5-second window expires; use ranged application to open, then commit with the sword
Bosses like Shido and Nue are explicitly weak to poison — the Hunter's Sword shreds them. But poison is weaker against some other Nushi, so keep your burst setup (see below) ready to swap to.
The Poison Build (Best Damage-Over-Time)
The Poison Build (Best Damage-Over-Time)
Poison builds are one of the most effective playstyles in Beast of Reincarnation — sustained damage over time instead of burst, letting you stay mobile and drain boss HP while avoiding risks.
Weapons (Emma):
- Hunter's Sword — the best melee weapon for Poison. It applies Poison Buildup on every hit, Poison lasts 5 seconds, and consecutive attacks refresh the duration. Excellent against bosses and elite enemies.
- Poison Arrows / Poison Bolts (ranged) — inflict Poison safely from distance, useful for opening fights and kiting.
Koo setup: prioritize Charms that add elemental effects (poison-related or status extension) and critical rate to multiply the DoT.
Spirit Stones: socket stones that boost poison application and damage where available.
Playstyle: stay aggressive enough to keep Poison active throughout the fight — refresh before it expires rather than letting it drop. Against elites, apply from range first, then commit with the Hunter's Sword once the status is ticking.
Other Viable Builds
Beyond Poison, the game supports several distinct loadout directions (the Boss Stealing system feeds into these):
- Stealth build — high single-target burst from stealth, best for clearing Nushi lairs cleanly; pairs with Koo's ranged Charms
- Ranged build — ammo and Koo-skill heavy; keeps Emma out of melee range while Koo does the damage
- Brute force / burst build — offensive stats and heavy weapons, for players who know the dodge timings; highest risk, highest clear speed
Some Nushi are much easier with a ranged or poison approach than with pure melee burst. If you're stuck, swapping one Charm and one weapon is cheaper than you think — keep a poison and a burst setup both ready.
Spirit Stones & Charms: Where to Farm
- Spirit Stones are upgrade materials for your gear — found from elite enemies and loot throughout zones. Prioritize collecting them from elite enemy encounters (marked on the map once discovered).
- Charms are found in the world and via identification (they start unidentified). Early-game Charm locations are concentrated in the first two zones — check the Game8 wiki's Charm guide for exact spots.
- Elite enemies (keeper golems, elite golems) are your best farming targets for both stones and rarer Charms.
Can You Respec?
Respec availability is a common question. Sources differ on the exact mechanics, but the community consensus is that some respec is possible through specific items/options — however, the safest early-game strategy is to not rely on it: plan your skill points, since respeccing may be limited or costly. If you're unsure, spend points only in the survival tree until you're confident in your build direction.
