LOCKED CRATES
Crates are found in the field and opened with a lockpick. Each attempt rolls independently: the pick can open the crate, break, or simply fail (nothing happens).
Open chance = clamp( round( 90 x pickTier / crateTier ), 10, 95 ) %
Break chance = clamp( base[pickTier] + 10 x |pickTier - crateTier|, 5, 95 ) %
Base break by pick tier: T1 75% · T2 55% · T3 35% · T4 20%. A larger tier mismatch adds 10% break per step, and a weaker pick also opens less often. Bringing a pick at least as strong as the crate is always best.
| Pick \ Crate | T1 crate | T2 crate | T3 crate | T4 crate |
|---|---|---|---|---|
| T1 | 90% open · 75% break | 45% open · 85% break | 30% open · 95% break | 23% open · 95% break |
| T2 | 95% open · 65% break | 90% open · 55% break | 60% open · 65% break | 45% open · 75% break |
| T3 | 95% open · 55% break | 95% open · 45% break | 90% open · 35% break | 68% open · 45% break |
| T4 | 95% open · 50% break | 95% open · 40% break | 95% open · 30% break | 90% open · 20% break |

CRATE LOOT
Every crate drops a number of stacks; each stack holds a quantity rolled per unit. Crates also have a chance of bonus items. Higher tiers give more, and T4 can drop Atmos Alloy.

| 1 |  Locked Wooden Crate | 2–3 | 8–20 | Seed Bundle (25%) |
| 2 | Locked Ironbound Crate | 2–4 | 10–25 | Seed Bundle (35%) |
| 3 | Locked Steel Crate | 3–4 | 12–30 | Seed Bundle (45%) |
| 4 | Locked Containment Crate | 3–5 | 15–40 | Seed Bundle (55%), Atmos Alloy (20%) |
