Santa Ladonna's starting javelin throw with a unique Duration-scales-Amount mechanic and one of the highest Luck damage ceilings in the game post-evolution.
The Santa Javelin is the only base-game weapon where Duration scales Amount instead of Duration. Per the Vampire Survivors wiki, the weapon throws a homing icicle javelin with a 1.0 second base Duration that determines how many copies fire in sequence. That means Spellbinder, the passive that nobody normally takes for damage, becomes a damage stat for Santa Javelin, and the math carries into the Seraphic Cry evolution where Duration directly multiplies the seraph beam count.
The other thing the wiki documents that most player guides skip is the post-evolution Luck cap. Per the Seraphic Cry wiki entry, the evolved weapon's damage scales with Luck up to a maximum of 11x at +900% Luck. From our experience, that ceiling is reachable in v1.13 endless runs through Limit Break Luck stacking, multiple Clover passives, and the Skull O'Maniac arcana. At full scaling the weapon outputs more single-target damage than most evolved weapons in the game.

Santa Ladonna and a stacked Luck buildAccording to the Vampire Survivors wiki, Santa Javelin throws homing icicle javelins toward the nearest enemy with a 6.5 second base Cooldown, a 1.0 second base Duration, and a 0.125 second projectile interval. The projectiles pierce, are not blocked by walls, and apply a knockback value of 1. Each cast has a 5% base critical hit chance with a 2x crit multiplier, and Luck scales the crit chance directly.
The signature mechanic is the Duration-as-Amount conversion. Per the wiki, every increase to Duration adds another javelin to each cast rather than extending an effect. That makes Spellbinder (the standard +Duration passive) into a damage multiplier on this weapon specifically. At base, the weapon throws 1 javelin with 1.0 second Duration; at max level it throws 3 with -1.5 second Cooldown; with a maxed Spellbinder stacking on top, the count climbs further into the Seraphic Cry evolution where the math really opens up.
Per the wiki stats panel, Santa Javelin ignores Speed (cooldown reduction) entirely, so 
Bracer's cooldown stat does nothing here. The damage levers are Might (raw multiplier), Area (100% base, 200% max), Amount (1 base, 3 max), Duration (which scales Amount), and Luck (which scales the 5% crit chance). Pool limit sits at 200, so the weapon almost never hits the projectile cap in normal play, even with Limit Break Amount stacks.
Take 
Spellbinder over a regular damage passive on this weapon. Per the wiki, Duration directly increases Amount on Santa Javelin, which means each Spellbinder level is functionally adding another javelin per cast. Most players skip Spellbinder because it does not affect their other weapons, but for Santa Javelin it is one of the strongest single passives available.
Per the wiki entry, here are the base and max-level stats. The Duration column matters more than usual on this weapon because Duration directly increases Amount:
| Stat | Value |
|---|---|
| Base damage | 20 at level 1, 70 at level 8 (+50 across levels) |
| Max level | 8 |
| Rarity | 60 |
| Starting weapon for | Santa Ladonna |
| Cooldown | 6.5 seconds base, 5.0 seconds at max (-1.5 seconds) |
| Duration | 1.0 second base (scales Amount, not effect length) |
| Projectile interval | 0.125 seconds |
| Area | 100% base, 200% at max (+100%) |
| Amount | 1 base, 3 at max (+2 javelins) |
| Crit chance | 5% base, scales with Luck |
| Crit multiplier | 2x |
| Knockback | 1 |
| Pool limit | 200 |
| Ignores | Speed (cooldown stat) |
| Unlock | Get Santa Javelin to level 7 in any run. |
Per the wiki, level Santa Javelin to 8 and pick up Clover at max level (level 5). Open any standard chest from minute 10 onward and the evolution triggers, with a first-time 500 gold reward. The max-level Clover requirement is the catch most players miss because Clover does not feel like a damage passive in its own right.
| Base weapon | Passive needed | Becomes |
|---|---|---|
| Santa Javelin (Lv 8) |  Clover (Lv 5, max) | Seraphic Cry |
Per the wiki, Seraphic Cry summons an array of seraphs that fire holy yellow light beams from the sky onto enemies. Each impact creates an Area-of-Effect shockwave. Like its base form, Duration increases Amount (more seraph beams per cast), but Duration also reduces individual shockwave Area and increases the interval between beams. The math gets unintuitive: stacking Duration adds beams but spreads them out and makes each shockwave smaller.
The standout feature is the Luck damage scaling. Per the wiki, Luck directly multiplies the weapon's damage up to a maximum of 11x at +900% Luck. That ceiling is reachable in endless runs through Clover passives stacked with Luck-boosting arcanas. From our experience this is the single highest single-target damage cap in v1.13 outside of Limit Break weapons, and it is why Santa Javelin builds typically beeline Clover at the expense of every other passive.
Per the wiki, while Seraphic Cry is on screen, every 
Rosary pickup transforms into a Weird Souls Purifier that creates four screen-clearing explosions on use. The drop weight of Rosaries is also tripled while the weapon is present, making them appear roughly three times as often from light sources and from the Hail from the Future (X) arcana. That is a fundamental change to the way pickups work in your run, and it stacks the deck heavily toward boss-wave clears at minutes 15, 20, and 25.
Stack the Hail from the Future (X) arcana with Seraphic Cry for free Rosary spawns. Per the wiki, the arcana creates additional Rosary drops, and Seraphic Cry both triples drop weight and converts every Rosary into a screen-clearing explosion. The two effects multiply on each other and turn boss waves into one-shot opportunities.
Santa Ladonna is the obvious home for Santa Javelin since the weapon is her starter and her +30% Luck plus +2 Armor opener directly buffs both the crit chance and the Seraphic Cry damage cap. Per the wiki, Santa starts with -70% Cooldown that depreciates by 20% per level (until -10% at level 4), so the early game does most of the cooldown work for you. The build below leans into Luck stacking for the post-evolution 11x damage ceiling and Spellbinder for the pre-evolution Amount ceiling.

Pummarolasurvivalbefore the Rosary HP-Critical procsThe build's clock is set by minute 10 like most v1.13 evolutions. The pacing trap with this specific weapon is the Clover max-level requirement: Clover takes 5 level-ups to cap, so every spare pick between weapon level 1 and 8 should go toward Clover before chasing other passives. Once Clover caps, leftover slots flow into Spellbinder, Empty Tome, and Candelabrador in that order, all of which directly scale Seraphic Cry's damage output.
According to the wiki, three arcanas stand out for this weapon. Gemini (I) creates a counterpart Santa Javelin called Levelin'Eh that levels up alongside the base weapon, mirroring its origin point. That is functionally a free second javelin per cast that benefits from Limit Break independently. Twilight Requiem (II) makes the icicles generate Curse-scaled explosions on impact, turning Santa Javelin into a secondary AoE. Tragic Princess (III) reduces cooldown while moving, which stacks naturally with Santa Ladonna's kiting playstyle.
For passives outside the core build, 
Skull O'Maniac stacks Curse, which buffs Twilight Requiem (II) explosions if you rolled that arcana. 
Stone Mask is a marginal pick if you are running Mad Groove (VIII) at minute 4 since the additional gold accelerates Greatest Jubilee farming for late-run Luck stacks. Avoid Bracer entirely. Per the wiki, Santa Javelin ignores Speed, so the cooldown reduction does nothing for the weapon directly.
Empty Tome instead, since Empty Tome stacks the Cooldown stat that Santa Ladonna's opener depreciates from. Empty Tome levels are what hold the cooldown floor after her -70% drops to -10% at character level 4.Per the Vampire Survivors wiki, Santa Ladonna costs exactly 666 gold to purchase after the survival unlock. That number is intentional. The same 666 thread runs through Pentagram (which never displays the damage number 666 even when the math lands there) and through Christine Davain's Sailor Moon-themed Pentagram synergy. The Devil's number is the running visual gag for Vampire Survivors' magic-themed character pool, and Santa Ladonna sits squarely in that pool despite the Christmas costume.
The wiki also documents an alternate unlock path. Players can skip the survival requirement by casting the spell "shesawit" in the Forbidden Scrolls of Morbane menu. That phonetically reads as "she saw it" and ties into Santa Ladonna's in-game flavor description, which says she "likes to keep secrets." The Rosary HP-Critical proc that triggers when she drops below low health fits the same visual motif, casting a saint's aura around the character at the moment of crisis.
Per the wiki, get Santa Javelin to level 7 in any run. The weapon then becomes available in the standard level-up pool for any character that does not already have it as a starter. Note this is one level short of the weapon's max level 8, so the unlock fires before the final upgrade.
It evolves into Seraphic Cry when held at level 8 alongside max-level (level 5) Clover. The chest must spawn after minute 10. Evolution rewards 500 gold the first time and dramatically changes how Rosary pickups behave for the rest of the run.
Per the wiki, Duration directly increases Amount on this weapon. That means every Spellbinder level adds another javelin per cast instead of extending an effect length. It is one of the only weapons where Spellbinder is a damage passive instead of a utility passive.
Per the wiki, Seraphic Cry damage scales with Luck up to a maximum of 11x at +900% Luck. That ceiling is reachable in endless runs through Clover stacks, Luck-boosting arcanas (Disco of Gold), and Limit Break Luck. At full scaling, Seraphic Cry has one of the highest single-target damage caps in v1.13.
Per the Santa Ladonna wiki entry, survive 20 minutes in The Laborratory stage. After unlocking, she costs 666 gold (scaling with character count). Alternatively, cast "shesawit" in the Forbidden Scrolls of Morbane to unlock her without the survival requirement.
No. Per the wiki, the bonus depreciates by 20% per character level until it sits at -10% at level 4. After that, you need Empty Tome stacks and weapon level scaling to maintain the cooldown floor. The opener gives you a 30 second window of dramatically faster casting before the bonus normalizes.
Might (raw damage), Area (100% to 200% at max), Amount (1 to 3 at max), Duration (which scales Amount), and Luck (crit chance and post-evolution damage). Per the wiki, the weapon ignores Speed entirely, so cooldown reduction passives do nothing for it directly.
Pre-evolution it is a strong mid-tier pick because of the Duration-scales-Amount mechanic. Post-evolution into Seraphic Cry with stacked Luck, it is one of the highest-ceiling base-game weapons in v1.13. See our weapon tier list for the full ranking against other base-game evolutions.
