Dino Hunters capture rate and capsules — math, ladder, and Tech Capsule swap alert

How p_catch is computed

The capture-rate calculator reads seven caller-supplied inputs and returns the effective probability that a weakened dinosaur accepts the chosen capsule. The math is:

Step 1  p_base       = rarity_base_catch[rarity]                         (probability 0–1)
Step 2  race_mod     = race_capture_luck_modifier[race]                  (decimal, 0 if unverified)
Step 3  p_base_race  = p_base * (1 + race_mod)                           (probability 0–1)
Step 4  CL_capsule   = capsule_capture_luck[capsule_tier]                (Capture Luck points)
Step 5  CL_dot       = dot_stacks * 15                                   (Capture Luck points / stack)
Step 6  CL_eff       = CL_capsule + CL_dot                               (Capture Luck points)
Step 7  CL_mod       = min(0.95, CL_eff / 100)                           (probability, capped)
Step 8  p_after_cl   = min(0.99, p_base_race + CL_mod)                   (probability 0–0.99)
Step 9  hp_mult      = max(0.05, 1.0 - target_hp_pct * 0.5)              (multiplier 0.05–1.0)
Step 10 p_catch      = clamp(p_after_cl * hp_mult, 0.001, 0.99)          (probability)

p_catch is the per-attempt catch probability. The geometric mean and inverse-CDF math then turn it into expected attempts and attempts to 50 / 80 / 95 % confidence.

The capsule ladder (Capture Luck vs. cost)

The Capture-Luck-per-Coin ratio jumps sharply at Elite: 320 CL for 7,200 Coins beats 300 CL for 159 Robux on both axes, and the calculator fires a dedicated swap alert every time Tech Capsule is selected. See Capsule ladder and pricing for the full side-by-side.

Race roll table and Emberwing bonus

The seven-row race roll table transcribed from the in-game race panel:

Emberwing’s bonus panel is the only one captured in public sources: DMG +15%, Capture Luck +12%, Rank Luck +5%, Hatch Speed +8%, EXP +2%. All other races render an [INFERRED] badge and contribute 0% to the calculator until Fishgig Game publishes numeric bonuses. See Races and Emberwing bonuses for the full discussion.

Worked example

Inputs: Legendary rarity, 20 % target HP, Elite Capsule, Emberwing race, 1 DoT stack, 80 % confidence target.

• p_base = 0.01
• p_base_race = 0.0112 (× 1.12)
• CL_eff = 320 + 15 = 335
• CL_mod = 0.95 (capped)
• p_after_cl = 0.9612
• hp_mult = 0.90
• p_catch = 0.8651 (86.5 %)
• Expected attempts ≈ 1.16 capsules
• N(80 %) = 1 capsule = 7,200 Coins
• N(95 %) = 2 capsules = 14,400 Coins

Verdict: Elite clears a Legendary in 1–2 attempts at low HP. Master (700 CL, 90,000 Coins) buys a few extra percentage points and is rarely worth the 82,800-Coin delta.

Edge cases the model handles

• Rarity unknown → defaults to Rare (0.15) with an “assumed Rare” note.
• target_hp_pct = 0 → hp_mult = 1.0; the slider models “would this catch land if I stopped shooting here?”
• target_hp_pct = 1.0 → hp_mult = 0.5, halving p_catch.
• Capture Luck overflow → CL_mod capped at 0.95.
• Probability never reaches 1.0 → p_after_cl capped at 0.99, p_catch clamped to [0.001, 0.99].
• Tech Capsule selected → Robux-vs-Coin side panel always rendered.
• Insufficient Coins → flag + recommend the cheapest capsule whose p_catch is within 5 percentage points.
• Free capsules (Basic / Fine) → cost-to-confidence is 0; display attempts only with a time-cost note in minutes of farming.
• Double Coins / Double Exp toggles → bit-identical zero delta on p_catch. The toggles exist to kill the community misconception.

Sources and verification

Verification date: 2026-08-01. The Capture Luck → p_catch mapping (Step 7) and the linear HP penalty (Step 9) are inferred from comparable Roblox simulator patterns; treat the on-screen in-game capture percentage as authoritative when it disagrees.
