Xyanyde
Xyanyde is an uncommon +1 mace in Baldur's Gate 3. Its signature effect can apply Faerie Fire after a missed attack, granting Advantage against the marked target and preventing it from becoming Invisible.
Key Takeaways
Xyanyde is a utility-focused uncommon +1 mace whose defining value comes from a miss-triggered Faerie Fire effect rather than exceptional raw damage.
Miss-triggered Faerie Fire
Xyanyde’s Fire can encase a target in Faerie Fire for two turns after the wielder misses an attack. The effect grants Advantage on subsequent attacks against that target and prevents it from becoming Invisible.
Limited activation
Xyanyde’s Fire can trigger only once per Short Rest, so its Advantage and anti-Invisibility utility are encounter tools rather than a continuously available weapon effect.
Minthara-linked acquisition
The mace is associated with Minthara in the Shattered Sanctum. It can be acquired by defeating her or by recruiting her, making its availability dependent on the player’s Act 1 route and choices.
A +1 mace with utility
Xyanyde is an uncommon +1 mace. Compared with an ordinary mace, its main distinction is the conditional Faerie Fire effect and related targeting utility, not a separately established damage advantage.
Mace weapon action
As a mace, Xyanyde provides Concussive Smash, a weapon action that can daze an enemy once per Short Rest.
Important story opportunity cost
Gale can consume Xyanyde to absorb its magical essence, permanently removing the weapon. Players who want to keep the mace should account for that camp interaction before donating it.
Overview
Xyanyde is an uncommon +1 mace in Baldur's Gate 3, best known for turning a missed attack into a temporary opening against the target. Its value comes from that utility rather than from being a general replacement for every other mace.
Xyanyde occupies a supporting role among Baldur's Gate 3's named early-game weapons. It is a one-handed mace associated with Minthara in the Shattered Sanctum, and it can enter the player's inventory through different outcomes involving her. That connection gives the weapon a meaningful place in the Underdark portion of progression without making it dependent on a single acquisition route.
The defining feature is Xyanyde's Fire. Once per short rest, a missed attack can inflict Faerie Fire on the target for two turns. This makes the miss more useful than an ordinary failed attack: while the effect lasts, attacks against the affected creature gain Advantage, and Faerie Fire also prevents that creature from becoming Invisible. The mace therefore supports follow-up attacks and can help expose enemies that rely on concealment.
That behaviour gives Xyanyde a different role from a plain enchanted mace. It is particularly relevant when a party can exploit Advantage immediately or when preventing Invisibility matters, while the effect is less central in fights where the party cannot capitalize on the short duration. Xyanyde also retains the standard mace action Concussive Smash, so its identity combines ordinary blunt-weapon use with a limited, miss-triggered control and visibility tool.
The weapon has additional story and inventory context. Its spiderweb engraving and reported Underdark origin distinguish its presentation from an anonymous roster weapon, while Gale can consume it to absorb its magical essence, permanently removing it from the inventory. That choice makes Xyanyde more than a simple equipment upgrade for a playthrough using Gale's magical needs, and players should treat consumption as a trade-off rather than a temporary unequip.
How to Obtain
- Act 1 access to the Goblin Camp and Shattered Sanctum for the defeat-and-loot route.
- For the alternate route, Minthara must remain recruitable and be recruited later; the two routes are mutually exclusive for the same playthrough outcome.
- 01In Act 1, reach the Shattered Sanctum in the Goblin Camp and defeat Minthara. Xyanyde can then be acquired from her as part of the encounter’s loot; this route requires resolving the Minthara encounter without losing access to her body.
- 02Alternatively, preserve Minthara for recruitment and recruit her later in the story. Xyanyde is associated with her equipment and can be acquired through that recruitment route rather than by killing her in the Shattered Sanctum.
Availability
Requires Minthara must be defeated or recruited into the party.
Xyanyde is tied to Minthara’s outcome in the Shattered Sanctum. The available acquisition route depends on the player’s story choice; no separate DLC, NG+, difficulty, or vendor-stock condition is established here.
Mechanics and Handling
Xyanyde’s defining combat behavior is its miss-triggered support effect rather than an added damage rider. The mace rewards continued pressure after an unsuccessful attack: a miss can turn the target into a more reliable target for the rest of the short encounter, provided the once-per-Short-Rest effect is still available.
Xyanyde’s Fire turns a miss into setup
Xyanyde’s Fire activates when the wielder misses an attack roll against a target. It encases that target in Faerie Fire for two turns, granting Advantage on subsequent attacks against the affected enemy. This makes the effect especially useful when a missed swing would otherwise waste the attacker’s action, or when the party is trying to focus down one important target. The ability can trigger once per Short Rest, so it should not be treated as a passive effect that applies to every miss.
The Faerie Fire effect also prevents the affected target from becoming Invisible. That gives Xyanyde a specific utility role against enemies that rely on invisibility: the mace can both improve the party’s attack consistency and help keep the target available for follow-up attacks. Its benefit is therefore conditional and tactical, not a universal replacement for a weapon with stronger direct damage or a more aggressive passive.
Mace actions remain available alongside the signature effect
Xyanyde also provides the mace weapon action Concussive Smash. This is separate from Xyanyde’s Fire and gives the wielder another short-rest-limited combat option that can Daze an enemy. Because both effects are limited resources, the weapon’s handling involves choosing between immediate control with Concussive Smash and reserving Xyanyde’s Fire for a missed attack or an enemy whose invisibility would otherwise disrupt the party’s targeting.
The weapon has no documented ammunition, reload, durability, or alternate firing behaviour. Its practical handling is consequently governed by ordinary melee positioning and by deciding when to spend its two special actions, rather than by resource management during a single attack sequence.
Do not sacrifice it casually when Gale is present
Gale can consume Xyanyde to absorb its magical essence. Doing so causes the mace to vanish permanently, removing its weapon actions and its Faerie Fire utility from the inventory. If the party intends to use Xyanyde as a combat weapon, confirm that it is not being selected for Gale’s magical-essence requirement before committing it.
Strengths, Weaknesses and Best Uses
Strengths
- Xyanyde’s Fire can apply Faerie Fire for two turns after the wielder misses an attack, granting Advantage on subsequent attacks against the affected target.
- Faerie Fire prevents the affected creature from becoming Invisible, giving the mace a specific answer to enemies that rely on invisibility.
- As a mace, Xyanyde provides Concussive Smash in addition to its unique effect; the action can daze an enemy once per Short Rest.
- Its +1 enchantment supports ordinary weapon attacks while its main distinction remains utility rather than a damage-only passive.
Weaknesses
- Xyanyde’s signature effect requires a missed attack, so its benefit is conditional and may not activate when the party needs it immediately.
- Xyanyde’s Fire is limited to once per Short Rest, restricting repeated use during encounters that lack time for recovery.
- Faerie Fire’s Advantage matters only while the marked target remains relevant and the party can make attacks against it; it does not improve every attack made with the mace.
- Using Xyanyde for Gale’s magical consumption permanently removes the weapon, creating an opportunity cost for keeping its combat utility.
Best uses
- Use it against enemies whose defenses include Invisibility, where Faerie Fire both reveals the target and blocks that escape condition.
- Keep it on a melee character who can continue attacking a marked target after the effect triggers, making the two-turn Advantage window useful to the party.
- Treat it as a utility-oriented mace for encounters where Concussive Smash or target exposure is more valuable than selecting a weapon with a purely offensive passive.

Lore and Design
Xyanyde’s lore gives the mace a strong connection to the Underdark and to Minthara. Its spiderweb-engraved head and unnatural cold reinforce that setting, while its item text attributes its casting to duergar slaves. The weapon’s association with Minthara is practical as well as narrative: it is encountered in the Shattered Sanctum alongside her story, and its fate depends on the player’s resolution of that encounter.
No documented developer commentary or broader design history is established for Xyanyde here. The available material supports describing it as an Underdark-themed weapon tied to Minthara, but not assigning a real-world inspiration or interpreting the spiderweb imagery as evidence of a deeper canonical relationship. Its lore significance is therefore specific rather than expansive: it helps identify the mace’s origin and story context without making it a major faction relic or plot artifact.
Trivia
- Xyanyde’s flavor text attributes its creation to duergar slaves in the Underdark and describes the mace as ice-cold to the touch, contrasting its spiderweb-engraved head with its association with Minthara.
- Xyanyde is one of the magical items Gale can consume for its arcane properties. Doing so removes the mace permanently, so players who want to keep it should avoid selecting it as the consumed item.
