Choose your reward
Pick one of three items drawn from the same rarity tier as your sacrifice.
That's the complete mechanic. Everything else in this guide is about playing it intelligently.
�?�� Important �??No Undo
The moment you drop an item into the Cauldron, the sacrifice is confirmed. There is no confirmation prompt and no way to retrieve the item if you change your mind after seeing the three options. Always be certain about the sacrifice before you drop it in.
Tier Rules �??What Goes In, What Comes Out
The Cauldron preserves rarity tier exactly. It cannot upgrade or downgrade. This is the only rule that governs what comes out.

The Cauldron's value scales inversely with item rarity. Commons and Rares are almost always worth Cauldroning because the pool of good ability items at those tiers is large and the sacrifice cost is low. Epics are often worth it �??you're trading a potentially mediocre Epic for a chance at Venom Bow, Emerald Bow, or another high-tier ability Epic. Legendaries are riskier: you might sacrifice a Pumpkin Lord for a worse Legendary, so consider carefully before throwing one in.
�??The Core Rule
Never Cauldron an item you actively want to keep. The Cauldron is for items that are occupying a slot without contributing meaningfully �??pure stat items with no abilities, items that don't suit your class, or items you've outgrown. If an item has a useful ability, think twice before sacrificing it.
What to Sacrifice
Always Cauldron These
Iron Helm (+15% armor), Basic Wand (+10% attack speed), Leather Boots (+8% move speed) �??any item with only a flat stat boost and no ability effect. These are placeholders. The Cauldron turns them into an ability item of the same tier.
Cracked Shield (+5% block chance), anything from the D-tier list. These items are statistically close to useless. Any replacement the Cauldron offers will be an upgrade. Throw them in without hesitation.
A Rare Defender item in an Archer's slot, or a Healer item on a Defender. Class-inappropriate items waste a slot entirely. Cauldron them �??the replacement pool draws from all items at that tier, including ones suited to your actual class.
Two items that apply the same effect (two attack speed items, two chill sources) have diminishing returns. Keep the better one and Cauldron the weaker one for variety. Exception: some builds deliberately stack duplicate effects for a specific synergy �??know your build before sacrificing.
Think Before Cauldroning These
Sacrificing a Legendary means drawing from the Legendary pool �??which contains the Pumpkin King and Iron Fortress, but also weaker Legendaries. If your Legendary has a genuinely useful ability for your build, keep it. Only Cauldron a Legendary if you're certain a better Legendary exists and your current one contributes nothing.
A B-tier item like Frost Wand is occupying a slot adequately. Whether you Cauldron it depends on what you need: if your build has three solid items and only needs one more ability item to come online, Cauldroning a B-tier for a chance at A-tier makes sense. If your loadout is weak everywhere, fix the worst slot first.
Never Cauldron These
Wand of Lightning, Pumpkin King, Emerald Bow, Iron Fortress. These items are build-defining. Sacrificing an S-tier for a shot at another S-tier has bad expected value �??the Cauldron pool at every tier contains more mediocre items than excellent ones.
If an item is the centrepiece of your run's build �??the Venom Bow in a Venom Sniper build, the Bleed Lance in a Bleed Stack build �??don't Cauldron it regardless of its tier. Losing the keystone unravels the entire build strategy.
When to Use the Cauldron
Timing matters as much as what you sacrifice. The Cauldron is available throughout the run, but some moments are better than others.
Between waves 1�??
Your item slots are mostly empty or filled with Commons. Cauldron any stat-only Common immediately �??there's nothing to lose and you need ability items to establish your build direction early.
�??Do It
Before a boss fight
The window between clearing the last wave and approaching the boss is the best time to Cauldron. You have breathing room, no enemies, and the most information about what your build needs. Use it to plug any dead item slots before the hardest fight on the map.
�??Do It
Mid-wave, during active combat
Using the Cauldron requires walking Tangy to it and interacting with the UI. That's time your towers are unmanaged, Tangy isn't attacking, and enemies are advancing. Only Cauldron mid-wave if your situation is desperate and a better item might save the run.
�??Avoid
When you have 3 bad items
Fix the worst slot first, then reassess. Don't Cauldron three items in one round if you can avoid it �??you need some stability to evaluate which replacements are actually improvements for your build direction.
Situational
When all 4 slots are strong
If every item slot is occupied by a B-tier or above ability item that suits your build, the Cauldron has low expected value. You'd be risking a working item for a chance at something marginally better. Save the interaction for when it genuinely addresses a weak slot.
�??Not Worth It
Even rounds in Endless Mode
In Endless Mode, using the Cauldron at the end of every even-numbered round (when you have a weak slot) maximises your chances of assembling a scaling build before enemy HP outpaces your flat damage. Consistent Cauldron use is the meta strategy for leaderboard climbing.

Frequently Asked Questions
Can the Cauldron produce the same item I sacrificed?
�??/span>
Yes. The Cauldron draws from the full pool of items at your sacrificed item's tier, which includes the item you put in. It's uncommon but possible. This is another reason not to Cauldron S-tier items �??you might sacrifice a Wand of Lightning and be offered another Wand of Lightning alongside two weaker options, having gained nothing.
Does the Cauldron pool change during a run?
�??/span>
The pool is fixed by tier and does not change based on what items you already own or have previously seen. Each use draws three random items from the tier independently. Using the Cauldron multiple times in the same run at the same tier does not improve or worsen your odds on subsequent draws.
Can I use the Cauldron multiple times per run?
�??/span>
Yes, as many times as you like, as long as you have items to sacrifice. There is no per-run usage limit. In Endless Mode, experienced players use the Cauldron repeatedly across many rounds to continuously upgrade weak slots as better items become available in the pool.
Is the Cauldron available on every map?
�??/span>
Yes. As of v1.0.3, the Cauldron appears on every map including Endless Mode. It is placed in a fixed location on each map �??typically near the shop or in a safe zone away from enemy paths.
Can I Cauldron items that are currently equipped on a tower?
�??/span>
Yes. Pick the item off the tower (unequipping it temporarily), carry it to the Cauldron, and drop it in. The tower will function without the item during the Cauldron interaction. Equip your new item on the tower immediately after to minimise the window where the tower is running without that slot.
Does the Cauldron work during a boss fight?
�??/span>
Mechanically yes �??the Cauldron can be used at any time, including during active boss fights. In practice, it's rarely advisable to use it mid-boss because walking Tangy to the Cauldron leaves your towers unmanaged during the most dangerous part of any map. Plan your Cauldron use before pulling the boss.
Common Mistakes
Hoarding bad items hoping to upgrade them naturally
The most common mistake. Players keep a D-tier Common in a slot for five waves because "maybe a better one will show up in the shop." The shop is random. The Cauldron is guaranteed. Use it.
Cauldroning a build keystone during a panic
When a run is going badly, the temptation is to throw everything into the Cauldron for fresh options. Don't sacrifice the items that are working. Identify which slot is actually the weak link and fix only that one. A run where one slot is weak is recoverable. A run where you've Cauldroned your Wand of Lightning for nothing useful is not.
Using the Cauldron mid-wave instead of between waves
Cauldron use takes Tangy out of the fight. Between waves is free time �??mid-wave is not. Even a short interaction window can let fast enemies bypass your Defenders while Tangy is walking across the map. The only exception is a truly desperate situation where a better item might prevent a loss.
Some players never use the Cauldron because they're worried about losing an item. This is the opposite mistake. A stat-only item in any slot is already failing you. The Cauldron is a free reroll �??the only cost is an item that wasn't contributing meaningfully. Don't overthink it.
