Sephiria Grimoire Build: Full Setup, Core Items & Run Sequence

Overview

The sephiria grimoire build focuses on dealing damage primarily through grimoire activations rather than basic attacks. Players who have tested this setup report that a grimoire with ghost synergy, combined with ice relics and life steal mechanics, can clear high-tier hard mode content. One player on the Steam forums described completing a "risk 30 clear" using a grimoire-with-ghost build alongside ice relics and life steal with bat, calling it one of the more effective setups they tried.

This guide covers the full grimoire build: what you need before starting, which core items to prioritize, the exact run sequence to follow, and how to recover when a run goes sideways.

What This Build Delivers

• Primary damage source: Grimoire activations (not left-click attacks)
• Support mechanics: Ice relics for area control, life steal for sustain
• Expected outcome: A build capable of clearing hard mode tiers when assembled correctly
• Difficulty: Moderate — requires understanding artifact priority and positioning

Requirements

Before attempting the full grimoire build, confirm you have the following:

Unlock Requirements

Talent Points

Community reports indicate that a Willpower 20 investment is the most effective way to enable grimoire-focused builds. This is not strictly mandatory — one player reported clearing Tier 37 with Wrath 20 and Swiftness 20 — but Willpower makes artifact selection and build realization significantly easier.

Optional but Recommended

• Luck 20: Multiple players describe this as nearly mandatory because it adds Wishing Fountain slots, which let you start with stronger artifacts. One player who beat Hard 30 said they "maxed out the luck" to make their build work consistently.
• All talent points unlocked: The build performs better with the full talent tree available, though it can work with fewer points at lower difficulty tiers.

Core Items

The grimoire build depends on specific artifact and relic combinations. These are the items that make the build function, based on player reports from the Steam community.

Essential Items

High-Priority Artifacts

• Frost Relic: Pairs with life steal for sustained recovery. One player described the combination as "easily cheesed" due to the healing volume.
• Frost Relic additional activation: Increases how often the relic triggers, which scales both damage and healing.

Items to Avoid

• Stormcloud + Magitech: While this is a powerful combo in its own right, it competes with the grimoire build for artifact slots. If you are committing to the grimoire path, skip lightning artifacts and focus on ice and ghost synergies instead.
• Windsong: One player noted that taking Windsong for attack speed while playing a grimoire build is a "silly build" that falls off at higher difficulty.

Run Sequence

Follow this sequence to assemble the grimoire build during a run. The order matters because early decisions determine which artifacts appear later.

Step 1: Start with the Right Talents

If you have Willpower 20 unlocked, start with it. If not, prioritize Luck 20 for the extra Wishing Fountain slots. Your starting artifacts set the tone for the entire run.

Step 2: Pick the Ghost Grimoire Early

Take the ghost grimoire as soon as it appears in the first shop or reward pool. This is your primary damage source, so you want it online before the mid-game.

Step 3: Collect Ice Relics

Prioritize any ice relic you encounter. The Flying Ice Spear was specifically mentioned by a player as allowing room clears without attacking. Even if you do not find that exact relic, ice relics in general support the build by controlling enemy movement.

Step 4: Add Life Steal Sustain

Pick up life steal mechanics — the bat synergy was specifically mentioned — once you have your damage core online. This keeps you alive during boss fights where grimoire cooldowns leave you vulnerable.

Step 5: Stack Frost Relic Activations

If you find Frost Relic, take it immediately. Additional activation upgrades are your highest-priority upgrades after the relic itself. This is what turns the build from "survivable" into "unkillable."

Step 6: Scale Into the Late Game

By the midpoint of the run, you should be dealing enough damage to clear rooms quickly. Continue taking ice relics and any artifact that increases grimoire activation frequency or damage. One player reported that their ice-only attack power reached about 45, which they considered average, yet they could still clear rooms without attacking — the grimoire was doing the work.

Step 7: Boss Execution

Against bosses, stay mobile and let the grimoire do the damage. Life steal keeps you topped up, but you still need to dodge heavy attacks. Players report boss kills in 2–3 minutes with this build when it is fully assembled.

Recovery and Common Mistakes

Even with a solid plan, runs can fail. Here is how to recover when the grimoire build is not coming together.

Missing the Ghost Grimoire

If the ghost grimoire does not appear by the end of Act 2, do not force the grimoire build. Pivot to whatever damage archetype the game is offering you. The build is strong, but it is not the only viable path — multiple players report clearing high tiers with companion builds, fire wand builds, and lightning crossbow builds.

No Ice Relics Found

Ice relics are important but not strictly required. If you have the ghost grimoire and life steal, you can still clear content — you will just be less efficient at clearing groups. Focus on single-target damage and play more carefully in rooms with many enemies.

Low Damage Output

If your DPS is below the ~800 threshold that players cite for clearing Hardmode Tier 37, check your artifact choices. Are you taking items that support grimoire activations? Are you accidentally picking up lightning or fire artifacts that dilute your build? Drop anything that does not serve the ghost/ice/life-steal core.

Taking Too Much Damage

If you are dying despite life steal, you may have skipped defensive relics. The grimoire build does not require heavy defense, but a single defensive relic or costume can make the difference. The Lizard Costume, which trades HP and defense for attack, is the opposite of what you want here — avoid it.

Early-Game Weakness

The grimoire build is weakest before you have both the ghost grimoire and your first ice relic. If you are struggling in the first two acts, consider taking a secondary weapon that covers your weaknesses. The staff pairs well with grimoires and provides its own damage trees — see the staff grimoire build for details.

Advanced Tips

Duplicate Artifacts

The Steam discussion mentions that Stormcloud gets "really broken if you have duplicate artifacts allowed." The same logic applies to the grimoire build: if your run allows duplicate artifacts, taking two Frost Relics or two ghost grimoire upgrades dramatically increases your output.

Costume Selection

The build does not require a specific costume, but you want one that does not punish your playstyle. Avoid costumes that reduce defense or HP, since you rely on life steal to sustain rather than raw tankiness.

Staff Synergy

The staff weapon, unlocked in Chapter 5, has a skill tree that includes lightning, cold, fire, attack speed, and max MP for blocking. The cold damage tree pairs well with the grimoire build's ice relics. If you have the staff unlocked, consider investing in its cold tree to complement your grimoire damage. For more detail, see the Sephiria staff build and the staff weapon wiki page.

Willpower Priority

If you are playing on hard mode and have access to all talent points, Willpower 20 is the single most impactful investment for this build. It does not lock you into a specific playstyle — it simply makes artifact choices more forgiving.
