Sammy is the best gold farming character in Vampire Survivors by a wide margin. This guide covers the 6,000 caterpillar unlock method with the exact Lake Foscari location, the gold-to-XP passive that breaks Game Killer, the full Vicious Hunger weapon strategy, and the meta gold farm build that generates hundreds of millions of gold per run.
Sammy is exclusive to the Tides of the Foscari DLC. Without the DLC, she cannot be unlocked by any method, including the spell code.
Sammy the Caterpillar is a rare enemy that spawns on Lake Foscari. Grinding random spawns would take hundreds of runs, so the correct approach is to head to the secret clearing where they spawn almost exclusively.
Cast the spell happybirthday in the Forbidden Scrolls of Morbane (Secrets menu) to unlock Sammy instantly. You still need to own the Tides of the Foscari DLC and pay the 50,000 gold cost.
Sammy's signature mechanic is unique in Vampire Survivors: every single gold coin she picks up also grants experience. This is why she is the king of gold farming.
When Sammy hits level 30, she automatically triggers Gold Fever and the background music switches to Happy Birthday (played once only). With a gold-focused build she reaches level 30 in under a minute, making the auto-trigger a reliable part of the run opening.
Sammy starts with -60% Might, meaning reduced damage. She recovers it in increments tied to the Fibonacci sequence:
| Level Reached | Might Bonus | Net Might |
|---|---|---|
| Level 2 | +10% | -50% |
| Level 3 | +10% | -40% |
| Level 5 | +10% | -30% |
| Level 8 | +10% | -20% |
| Level 13 | +10% | -10% |
| Level 21 | +10% | +0% (neutral) |
Since Sammy gains XP from every coin pickup, she blasts through these levels in seconds. The -60% penalty is functionally irrelevant after the first 30 seconds of any gold-farming build.
Sammy starts with Vicious Hunger, which is already the evolved form of Gatti Amari. Unlike most characters, Sammy does not need to worry about weapon evolution.
Summons giant cat eyeballs with hexagrams that travel in straight lines from the edge of the screen, dealing 30 damage on contact. The critical feature is its gold transmutation: defeated enemies and pickups have a chance to turn into gold coins.
This means every enemy killed with Vicious Hunger at high Sammy levels is essentially guaranteed to drop gold, which in turn levels Sammy up faster, which increases the gold chance further. Classic exponential runaway.
Vicious Hunger can union with Soul Steal to form Power of Lire. This was originally unique to the Master Librarian but was added to the weapon pool in late 2025. It is a massive gold-generation weapon. However, for pure gold farming runs, avoid the union: it reduces survivability and slightly lowers conversion efficiency compared to keeping Vicious Hunger standalone with Limit Break maxed.
Sammy's stage choice depends on whether you are farming gold or doing a normal survival run.
| Stage | Rating | Why |
|---|---|---|
| Moongolow | S-tier | Best gold farming stage in the game. Pot-breaking generates gold coins that feed Sammy's XP loop. Highest gold multiplier from destructible objects. |
| Lake Foscari | A-tier | The Sammy unlock stage. Has the hidden Sammy caterpillar zone plus natural pickups. Good for unlock grinding and Gold Fever chains. |
| Space 54 | A-tier | Abundant pickups, strong for Sammy with Disco of Gold. Performance can drop at extreme levels though. |
| The Bone Zone | B-tier | Highest stage gold multiplier, but enemies scale with time and player level. Risky at low egg counts. Better after Limit Break unlocks. |
| Cappella Magna | B-tier | Standard stage. Works for normal Sammy runs but nothing special for gold. |
| Arcana | Priority | Why It Works |
|---|---|---|
 Disco of Gold (XV) | Must have | The single most important arcana for Sammy. Converts gold pickups into healing and multiplies gold generation. Also extends Gold Fever duration dramatically. |
 Wicked Season (XIII) | Must have | Every level-up increases a random stat (Growth, Luck, Greed, Curse). Combined with Sammy's insane level-up speed, this snowballs stats harder than any other arcana. |
 Sarabande of Healing (VI) | High | Doubles healing from food pickups. Stacks with Disco of Gold's healing conversion for near-immortality. |
 Hidden Anathema (III) | Medium | Amplifies food-based bonuses. Strong if you are running the Darkasso relic. Requires Ode to Castlevania DLC. |
| Item | Priority | What It Does |
|---|---|---|
 Paranormal Scan | Must have | The only passive worth taking in a farming build. Provides uncapped stats without consuming a weapon slot. |
 Clover (Luck) | High | Luck directly multiplies Vicious Hunger's gold transmutation chance. More Luck equals more gold equals more XP. |
 Torrona's Box | Medium | Curse stacking increases enemy count, giving Vicious Hunger more transmutation targets. |
 Stone Mask | Medium | Greed stat directly multiplies coin value and healing from Disco of Gold. Stack if possible. |
For pure gold farming, take NO other weapons besides Vicious Hunger. Extra weapons increase lag, waste Limit Break rolls, and reduce gold generation. Paranormal Scan is the only exception worth taking.
This is the optimized meta build for maximizing gold per run. Expect hundreds of millions to billions of gold depending on Golden Egg investment and run length.
Vicious Hunger at extreme Limit Break stacks can tank your frame rate. If the game starts lagging, quit early, bank the gold, and start a fresh run. Shorter runs at higher Greed yield more gold per real-time minute.
Sammy is a playable character added in the Tides of the Foscari DLC. She is designed around gold generation: every coin she picks up also grants experience, her starting weapon (Vicious Hunger) transmutes enemies into gold, and she triggers automatic Gold Fever at level 30. Widely considered the best gold farming character in the game.
Defeat 6,000 Sammy the Caterpillar enemies on Lake Foscari. The fastest location is a hidden area northeast of the starting zone, reached through a hedge maze. Once unlocked, Sammy costs 50,000 gold to purchase (cost scales with characters owned). Alternatively, cast the spell happybirthday in the Forbidden Scrolls of Morbane.
Head to the northeast quadrant of Lake Foscari. Enter the hedge maze slightly northeast of your spawn point. Go right, then take the second upward path to the top, then left, then take the first downward path to exit. This drops you into a secret clearing where Sammies spawn almost exclusively. Bringing area-of-effect weapons (Axe, Holy Water, Garlic) and Curse items dramatically speeds up kill count.
Sammy has a unique passive where every gold coin picked up grants experience at a 1:1 ratio (modified by stage gold multiplier, Greed, and Growth). This is the only way to level up the Game Killer (0) arcana. Chests and level-up rewards do not grant experience. The internal function name is AddXP_IgnoretGameKiller, so it is intentional.
Vicious Hunger is Sammy's starting weapon. It is actually the evolved form of Gatti Amari (evolved with Stone Mask). Summons giant cat eyeballs that travel in straight lines, dealing damage on contact. It has a chance to transmute enemies and pickups into gold coins. Sammy enhances this, increasing the gold chance from 0.5% to 16.5% at base, scaling up to 65% at level 98.
For gold farming: use one weapon only (Vicious Hunger), add Paranormal Scan as the only passive, enable Limit Break, and pick Wicked Season (XIII), Disco of Gold (XV), and Sarabande of Healing (VI) as arcanas. Play on Moongolow (highest gold stage). Expect hundreds of millions of gold per 15-minute run.
No, not for gold farming. Adding more weapons increases lag and reduces gold generation. Limit Break rolls are wasted on other weapons instead of stacking Vicious Hunger. The only exception is Paranormal Scan (technically a passive, not a weapon) which grants stats without consuming a weapon slot. For a normal survival run, you can play with other weapons but Sammy is weak combat-wise until level 21.
Power of Lire is a union (double evolution) that combines Vicious Hunger with Soul Steal. Previously unique to the Master Librarian, it was added to the weapon pool in late 2025. It is a massively powerful gold-generation weapon. For pure farming though, do not union Vicious Hunger into Power of Lire: survivability drops and gold conversion is slightly lower.
When Sammy reaches level 30, she automatically triggers a Gold Fever and the background music switches to Happy Birthday (played once). This is a reference to Colin the Caterpillar, a UK birthday cake that inspired Sammy's design. Reaching level 30 is trivially fast thanks to the coin-to-XP passive.
It is an intentional early-game weakness. Sammy gains +10% Might at levels 2, 3, 5, 8, 13, and 21 (the Fibonacci sequence), fully recovering at level 21. Since Sammy levels up incredibly fast from coin pickups, this -60% penalty lasts only a few seconds in practice.
