BG3 Amulet of Greater Health: The CON 23 Breakpoint Every Tank Player Needs to Know

Verified on BG3 Patch 7. Mechanics subject to change with future updates.

The Amulet of Greater Health sets your Constitution to 23 and grants advantage on Constitution saving throws. For some builds that is transformative — for others it wastes the neck slot. This guide breaks down the exact HP math by starting CON, the concentration save probability gain, and the builds that genuinely profit versus the ones that should look elsewhere.

What the Amulet of Greater Health Does

The tooltip reads: “Sets the wearer’s Constitution score to 23. The enchantment has no effect if their Constitution score is higher without it.” That second sentence matters — if you somehow reach CON 24 through other means, the amulet is a dead item. Almost no build hits that threshold without it.

The secondary effect — advantage on Constitution saving throws — is where the real value hides for spellcasters. Every time you take damage while concentrating on a spell, you make a Constitution saving throw (DC = max of 10 or half the damage taken). Advantage means you roll twice and take the higher result instead of praying to a single d20 plus your modifier [6].

One mechanic worth knowing: equipping the amulet raises your HP maximum but does not restore current HP to match. Out of combat, you can equip, unequip, and re-equip the amulet to trigger a recalculation that restores HP to the new maximum — zero resources spent. This makes it a reliable out-of-combat heal for any build running it [1].

How to Get It (House of Hope, Act 3 Only)

The amulet sits on a pressure-plate trap in the House of Hope Archive. There is no Act 1 or Act 2 method to access it.

1. Reach Baldur’s Gate Lower City in Act 3 and locate Devil’s Fee, the arcane shop.
2. Speak to Helsik. She sells access to the House of Hope for 20,000 gp — persuasion and other checks can bring this down to 10,000 gp. You can also pickpocket the ritual components directly [5].
3. Perform the ritual on her upper floor to open the portal.
4. Navigate through the Foyer, Feast Hall, and Main Corridor to reach the Archive.
5. At the Archive’s leftmost pedestal (X: -6548, Y: 2940), disarm the pressure plate with a DC 20 Sleight of Hand check — or swap the amulet with an equal-weight item to avoid triggering it [1].
6. Picking it up while NPCs are watching turns the entire area hostile. Sneak or clear the room first.

The Gauntlets of Hill Giant Strength occupy the northern pedestal in the same room — worth grabbing if you’re running a Strength-based build. For full context on Act 3 progression leading to this area, see our BG3 Act 3 guide.

The CON 23 Breakpoint: What the Numbers Actually Mean

CON 23 gives a +6 modifier — the same as CON 22. The amulet puts you one point above a modifier breakpoint, which means the advantage on saving throws is doing more work than the raw score suggests. You’re not getting a higher modifier than someone at CON 22; you’re getting advantage on saves stacked on top of that +6.

For HP, the modifier applies retroactively to every level you have. At Level 12:

The class has no effect on the CON mod contribution to HP — the modifier is added every level regardless of hit die. A Barbarian and a Wizard wearing the amulet both gain exactly 72 HP above a CON 10 baseline [3]. The difference is how much 72 HP matters relative to their existing total.

Barbarian Unarmored Defense: If you play without armor, your AC is 10 + DEX modifier + CON modifier [4]. Moving from CON 16 (+3) to CON 23 (+6) adds 3 AC — equivalent to going from leather armor to chainmail without breaking Unarmored Defense. Whether that’s worth the neck slot is a different question (covered below).

The Withers Stat-Swap: The Optimization Most Guides Miss

The most impactful way to use this amulet isn’t just equipping it — it’s building around it from character creation.

1. Character creation: Set CON to 8. Redistribute those saved points to your primary spellcasting stat — INT for Wizard, CHA for Sorcerer or Paladin, WIS for Cleric or Druid.
2. Acts 1 and 2: You have low HP. Manage this with positioning, Misty Step, and healing word from a party Cleric. This is an optimization play, not a beginner approach.
3. Act 3, House of Hope: Acquire the amulet.
4. Withers respec (100 gp at camp): Put CON at 8, pour every freed point into your primary stat.
5. Result: CON 23 from the amulet plus 2—4 more points in INT, CHA, or WIS than a standard build allows.

For a Paladin, pumping CHA from 17 to 19 adds that bonus to Aura of Protection — a flat saving throw bonus for your entire party, not just yourself. For a Wizard, extra INT raises spell save DC and spell attack rolls on every spell for the rest of the game. The Act 3 gate is the catch: you need a plan for surviving Acts 1 and 2 with 8 CON.

Which Builds Gain the Most

Four factors determine how much you benefit: starting CON, whether you concentrate spells, whether you have CON save proficiency, and what amulet slot competition looks like in your build.

Concentration Wizards: The Highest Ceiling

Wizards typically run CON 8–14 and have no Constitution saving throw proficiency without the Resilient feat. In Act 3 fights — the Iron Throne, Cazador’s arena, the House of Hope itself — enemies deal enough single-hit damage to fail a CON 10 DC concentration check on a flat d20. With the amulet, you roll twice at +6, making those saves reliable instead of coin-flip outcomes.

The spells worth protecting are the game-changers: Hypnotic Pattern (crowd control for 7+ enemies), Wall of Fire, Black Hole, and Hunger of Hadar. Losing concentration on any of those mid-fight is a wasted action and potentially a lost encounter. Our Evocation Wizard build prioritises this amulet above every other neck-slot option in Act 3.

Paladins: The Most Overlooked Case

Paladin is the build where players consistently underestimate the amulet. Paladins have no Constitution saving throw proficiency — they concentrate spells (Bless is the best buff in the game per action-economy value, plus Wrathful Smite and Branding Smite) while standing on the frontline taking hits. The amulet solves both problems simultaneously, and every CHA point freed from CON investment goes into Aura of Protection, which scales your entire party’s saving throws. Check our BG3 Paladin build guide for the full CHA-first stat allocation.

Which Builds Should Skip It

Three builds have strong reasons to keep the neck slot for something else:

Warlocks get more mileage from the Spellcrux Amulet (also Act 3), which restores a spell slot once per short rest as a bonus action. Warlocks run 2–4 slots at most levels — an extra slot per short rest doubles their leveled-spell output. HP is also less critical because Warlocks deal damage from range via Eldritch Blast rather than taking frontline hits.

Fighters already have CON saving throw proficiency baked in from level 1. The advantage on saves is partially redundant, and most Fighter subclasses don’t concentrate spells. The Necklace of Elemental Augmentation boosts elemental damage on every weapon attack — a stronger pick for most Fighter builds. Our Fighter build guide covers the Act 3 neck-slot options in detail.

Barbarians already invest CON to 16–18 for Unarmored Defense and hit point scaling, and they have CON save proficiency. The +3 AC gain from CON 16 to CON 23 is real, but the Periapt of Wound Closure — which doubles HP restored during short rests — often wins for a class built around short-rest recovery. If your neck slot is otherwise unoccupied and you’re running a non-rage-dependent build that wants AC, consider it; otherwise, look elsewhere. Our Wildheart Barbarian build guide walks through this trade-off.

Frequently Asked Questions

Does the Amulet of Greater Health stack with other CON-boosting items?

It sets CON to 23 rather than adding to it, so it doesn’t stack with other CON bonuses — but it has no interaction with Strength-boosting items like the Elixir of Cloud Giant Strength. Running Cloud Giant Elixirs on a Tavern Brawler Barbarian while wearing the amulet works fine because they affect different ability scores.

Can I get this before Act 3?

No. The House of Hope is only accessible after reaching Baldur’s Gate in Act 3 via Helsik at Devil’s Fee. No method bypasses this gate — the portal requires completing specific Act 3 story beats to unlock. Plan your build around its absence for the first two acts.

Does equipping it also increase my party members’ HP?

No — the amulet only affects the wearer. To boost party max HP, use the Cleric’s Aid spell, which scales with spell slot level and raises the HP maximum of up to three targets simultaneously, regardless of who wears what.
