The Large Gourd farm, from zero
| Metric | Value |
|---|---|
| Cost per Large Gourd | 8,800 Wen |
| Slayer Progress per Gourd | +300 |
| Gourds needed from 0 Progress | 37 |
| Total Wen from 0 Progress | ~325,000 |
| Progression reached | Slayer Progress Lv 4 (Max) |
| Breathing Boost duration | ~15.2 seconds |
Permanent stats along the way
- Slayer Progress Lv 3: +25 Max Stamina, +75 Max Health, +0.07 Max Health Factor.
- Slayer Progress Lv 4: an additional +100 Max Health and +0.08 Max Health Factor and a new skill called breathing boost
These stat bumps land permanently as you climb the bar — they're not tied to activating the Breathing Boost itself, so the grind pays off even before you use your first boost.
