She-Moon Eeta storyline. 5,000 starting coins, 15 unlocks, completion grants the Reborn skin.
To End an Ice Age is one of three base-game Adventures that unlocks after collecting the Atlas Gate relic in Boss Rash. The wiki specifies the adventure opens with 5,000 starting coins, runs 15 unlocks across the 5 chapters, and pays out 35,000 gold plus the Reborn She-Moon Eeta skin as the completion reward. It is the longest of the three base-game Adventures by chapter count and the only one with a Planar Bazaar shop entry.
The buried mechanic is the gated item collection. According to the wiki, each chapter has a coffin that unlocks the next chapter when opened. The adventure also limits the item pool to a specific 20-item subset: Whip, Bloody Tear, Magic Wand, Holy Wand, Cross, Heaven Sword, Pentagram, Gorgeous Moon, Clock Lancet, Laurel, Vento Sacro, Fuwalafuwaloo, Glass Fandango, Celestial Voulge, Spinach, Armor, Hollow Heart, Wings, Clover, and Crown. Standard builds that lean on Garlic or King Bible cannot use them here.
Build context. The wiki notes 9 playable characters in this adventure: She-Moon Eeta as the central character, plus Mortaccio, Bianca Ramba, Cosmo Pavone, Christine Davain, Exdash Exiviiq, Toastie, Smith IV, and Gazebo. Each one unlocks at a specific in-adventure milestone, so character selection changes as the run progresses. Cosmo Pavone is a hidden-character unlock tied to the Chapter 4 firebird storyline.
This guide covers the unlock chain from Boss Rash, the 5 chapter progression with modifier rules, the character roster and unlock conditions, the limited item pool, the Planar Bazaar shop access, and the mistakes that soft-lock the adventure on the Cosmo Pavone coffin transition.
Collect the Atlas Gate relic in Boss Rash. This opens all three base-game adventures (A Garlic Paradise, World of Light and Dark, and To End an Ice Age).
Reborn She-Moon Eeta skin plus 35,000 gold coins. Skin applies to the She-Moon character on standard runs after completion.The adventure gates behind a single relic. Per the wiki, the Atlas Gate drops in Boss Rash, the challenge stage that unlocks after activating Hyper mode on all 5 normal stages. The same relic opens all three base-game Adventures in a single pickup, so the unlock cost is one Boss Rash run regardless of which adventure the player wants first.
| Step | Requirement |
|---|---|
| 1. Unlock Hyper mode on all 5 normal stages | Defeat the 25-minute boss on Mad Forest, Inlaid Library, Dairy Plant, Gallo Tower, and Cappella Magna |
| 2. Unlock Boss Rash | Activate Hyper mode on all 5 normal stages (same trigger) |
| 3. Collect the Atlas Gate in Boss Rash | The relic drops during a standard Boss Rash run. Picking it up opens the Adventures menu |
| 4. Select To End an Ice Age | From the Main Menu, choose Adventures, then pick To End an Ice Age. The adventure starts as a semi-new save with 5,000 starting coins |
Per the wiki, the adventure runs on its own progression track separate from the main save. Unlocks earned inside To End an Ice Age stay inside the adventure during the playthrough, but completion grants standard-pool rewards (the Reborn She-Moon Eeta skin) that carry over to the main save when the adventure ends.
Each chapter unlocks the next via a coffin in the previous stage. According to the wiki, the chain runs Ice Age into Ice Cream into A Fiery Apparition into A Pure Heart and ends at The Rebirth, The Return. Each stage carries its own time limit, modifier set, and theming from the She-Moon Eeta storyline.
| Chapter | Stage | Time | Modifiers |
|---|---|---|---|
| 1 | Ice Age | 20:00 | +35% Move Speed (default unlock) |
| 2 |  Ice Cream | 30:00 | +25% Move Speed, +20% Gold |
| 3 |  A Fiery Apparition | 30:00 | +25% Move Speed |
| 4 |  A Pure Heart | 15:00 | +25% Move Speed, +100% XP |
| 5 |  The Rebirth, The Return | 20:00 | +35% Move Speed, -75% XP |
Per the wiki, the XP modifiers on Chapters 4 and 5 invert dramatically. A Pure Heart doubles XP gain to compress level-ups into the 15-minute window, which makes evolution unlocks happen on a tighter timeline than standard stages. The Rebirth, The Return then cuts XP by 75%, which inverts the pattern and forces high-damage builds to compensate for the slow level climb.
Chapter 4's +100% XP bonus on a 15-minute time limit is the fastest level-up window in the adventure. In actual play, this is the right chapter to grind evolution-gate unlocks like Wings, Crown, or Spinach if the player needs those items for the post-adventure runs. The Rebirth, The Return inverts this with -75% XP, so reserve level-up needs for Chapter 4 specifically.
The adventure carries 9 playable characters per the wiki. She-Moon Eeta is the lead and the only character available at the start. The other 8 unlock through chapter-specific coffins, level milestones, or hidden character mechanics that mirror the standard Vampire Survivors unlock patterns.
| Character | Role in adventure |
|---|---|
 She-Moon Eeta | Starting character. Lead of the adventure storyline |
 Mortaccio | Chapter 2 companion. Bone-rattling skeleton storyline |
 Bianca Ramba | Chapter 3 companion. Fiery insults at Mortaccio |
 Cosmo Pavone | Chapter 4 firebird. Hidden-character unlock route |
 Christine Davain | Recurring companion across multiple chapters |
 Exdash Exiviiq | Unlock: Survive 10 minutes with Cosmo Pavone |
 Toastie | Unlock: Survive 20 minutes with Cosmo Pavone |
 Smith IV | Unlock: Survive 30 minutes with Cosmo Pavone |
 Gazebo | Unlock: Reach Level 40 with She-Moon Eeta |
According to the wiki, the Cosmo Pavone unlock chain alone delivers three secret characters (Exdash, Toastie, Smith IV) tied to in-run survival time. This makes Cosmo Pavone the most unlock-dense character in the adventure once players figure out the firebird hidden mechanic, which requires Chapter 4 to be accessible.
The adventure restricts the weapon and passive pool to a specific subset. Per the wiki, the available items are 8 weapons, 4 evolutions, and 8 passives. This is a deliberate constraint on the standard 50+ item roster, and builds that lean on items outside this list cannot function inside the adventure runs.
| Type | Items in pool |
|---|---|
| Base weapons | Whip, Magic Wand, Cross, Pentagram, Clock Lancet, Laurel, Vento Sacro, Glass Fandango |
| Evolutions | Bloody Tear, Holy Wand, Heaven Sword,  Gorgeous Moon, Fuwalafuwaloo, Celestial Voulge |
| Passives | Spinach, Armor, Hollow Heart, Wings, Clover, Crown |
The wiki notes additional item-based unlocks earned inside the adventure: 
Fire Wand, 
Bracelet, 
Santa Water, 
Shadow Pinion, and 
Parm Aegis. Each one unlocks for the main save when discovered inside the adventure, which means the adventure doubles as a passive-collection grind for players who have not unlocked those items via standard stages.
In actual play, Vento Sacro plus Fuwalafuwaloo is the strongest in-pool damage chain. Per the wiki, both are available, both scale off the walking-distance bonus mechanic, and the pool restriction actually helps the build by reducing the choice space on level-up screens. Pick Vento Sacro early, max it for the Fuwalafuwaloo union, and the build carries through all 5 chapters.
Planar Bazaar is a unique shop stage in this adventure. According to the wiki, it unlocks at character Level 80 and runs a 30:00 timer where the in-game clock stays frozen at 00:00. The +25% Move Speed and +25% XP Bonus modifiers stack the standard adventure modifiers, and the stage itself acts as a meta-shop for items collected across multiple adventures.
| Property | Value |
|---|---|
| Stage | Planar Bazaar |
| Unlock | Reach character Level 80 |
| Time limit | 30:00 (clock frozen at 00:00) |
| Base modifiers | +25% Move Speed, x0 Clock Speed |
| Hyper modifiers | +25% Move Speed, +25% XP, x0 Clock Speed |
| Theme | Cross-adventure shop hub |
Per the wiki, the frozen clock means enemies do not scale with timer progression the way they do in normal stages. The shop frame applies to multiple adventures, not just To End an Ice Age, which makes Planar Bazaar a centralized location for cross-adventure trades and rare-item purchases. Reaching Level 80 inside the adventure is the gating step, so the leveling pace of Chapter 4 (+100% XP) is the natural lane to unlock the shop.
Pair the To End an Ice Age adventure with the standard-stage spokes for the items the adventure introduces and the broader build context.
