Quick Stats
| Type | Store Trinket |
| Effect | +15% Stamina Regeneration |
| How to Get | 1250 Ichor + survive 50 Floors |
| Best For | High-Stamina Toons, Whispering Flower pairing |
| Verdict | Modest — reliable but outclassed by Items |
Effect Explained
Thermos' effect is a flat 15% Stamina Regeneration increase — the only Trinket that consistently boosts regen (Star Pillow only works while extracting; Feather Duster requires Items).
The math honesty: 2.4/s becomes 2.76/s — helpful when running often, but 15% isn't much. Common Items like Pops (and similar) are usually better value for stamina sustain.
Who benefits: - High-Stamina-capacity Toons: the regen boost matters more with a big pool. At best (270 Stamina), full regen is ~14.7 seconds faster; at worst (120 Stamina), only ~6.5 seconds. - Late-game runs: after Dyle's Floor and/or with both cooldown Cards, nearly every Toon gets slightly faster regen.
The Whispering Flower pairing: Thermos + Whispering Flower + Astro with 3 Items = 150.1% stamina regeneration (6/s) — the highest permanent regen in the game. As Bassie with 4 Items, it's 84% (4.42/s). Without Astro/Bassie, the pair gives 66.8% (4/s) — effectively Astro's Well Rested passive, at the cost of 2 Trinket slots and 3 inventory slots (not very recommended).
The verdict: for most players, a different stamina-regen Trinket or Items bring more impact. Thermos is a solid-but-modest foundation for stamina builds.

Best Toon Combos
- High-Stamina Toons: the regen boost scales with pool size.

- Late-game runs: marginal speed-up for everyone.
- Avoid if you rely on Items for stamina — Pops and similar are better value.
