How the Ultra Rank and Boss Readiness tool works

The tool reads caller-supplied values across four buckets — current resources, farm rates, weapon + team + equipment, and target boss — and returns:

• Material gap sorted by bottleneck priority (DNA Core > Crimson Flame Scale > SSS fodder > Coins).
• Projected time-to-Ultra in hours (Coins branch) or weeks (SSS / DNA / CFS branches), with the slowest branch as the total.
• Boss Readiness Score (0–100) with a five-component breakdown.
• Weapon upgrade ROI for the next 5 levels.
• Fastest-path recommendation as an ordered action list with cost-benefit rationale.
• ULTRA READY flag with the next-click path.

The Ultra Rank cost vector

Ultra_Rank_Cost(dino) = {
  coins: 17_000_000,
  dna_core: 1,
  crimson_flame_scale: 1,
  sss_fodder: 3
}

The cost is identical for every Ultra-eligible dinosaur. The Raptor Nest Raid is the only documented source of DNA Core, so the gate is effectively RNG-locked behind Lottery Tickets.

Bottleneck priority

The calculator sorts the gap table in this order:

The “fastest path” recommendation targets priority 1 first, then 2, 3, 4. When every gap is 0, the calculator flips to “All gates satisfied; pick a harder boss.”

Projected time-to-Ultra

The slowest finite branch dominates total_days. If any branch is BLOCKED, the calculator surfaces BLOCKED on <resource> instead of a numeric days estimate.

Boss Readiness Score (0–100)

Weapon (0-40):   tier_pts (4 / 12 / 16 / 22 / 30) + dps_norm (up to 10)
Team (0-25):     (T_rank_avg/9) * 15 + min(T_level_avg/80, 1) * 10
Equipment (0-15): min((E_dmg/90 + E_hp/1500 + E_def/20)/3, 1) * 15
Race (0-10):     10 if Race_dmg >= 15% else 5 * (Race_dmg/15%)
HP safety (0-20): neutral 10 if Boss_min_dps == 0 else min(T_dps / Boss_min_dps, 2.0) * 10

The score rolls up to a single number; the calculator also breaks out each component so you can see which subsystem is bottlenecking your readiness.

Weapon upgrade ROI

For each of the next 5 levels above your current upgrade level:

cost_k        = 100 + (k - 1) * 50
cum_cost_k    = Σ cost_i
dmg_k         = W_dmg * (1 + 0.10 * (k - W_upg_lvl))
dps_k         = dmg_k / W_cd
uplift_k      = (dps_k - W_dmg / W_cd) * DROP_RATIO * 3600
payback_k     = cum_cost_k / max(uplift_k, 1)
roi_flag_k    = payback_k <= TARGET_PAYBACK_HOURS (default 8h)

The default 8-hour payback target lets the calculator flag the next upgrade as “Yes” or “Skip”.

Fastest-path recommendation

Once the gap table and the ROI table are filled, the calculator ranks action items by:

1. Highest-payback weapon upgrade with roi_flag = true.
2. Bottleneck resource the gap table sorts to the top.
3. Boss Readiness component scoring the lowest (the next subsystem to upgrade).

The output is an ordered list with cost / benefit rationale, capped at the top 5 actions.

What’s not in the tool

• DNA Core per-ticket drop rate — not published; default 0 → Infinity branch → BLOCKED.
• Boss minimum DPS — not published for Triceratops, Blazemane Rex, or Raptor Nest raid bosses; default 0 → HP safety neutral 10.
• Crimson Flame Scale per-raid drop rate — not published; same BLOCKED handling.
• Weapon DPS cap above Combat Shotgun — 112.5 DPS is the verified maximum. Venom Grenade Launcher stats are not published.

Limitations

• Linear weapon upgrade cost is approximate for early levels; late-game upgrade curves deviate.
• The 17M-Coin Ultra Rank requirement implies an exponential step that is not closed-form.
• DNA Core / Crimson Flame Scale drop probabilities are scenario inputs; supply your own measured values to break BLOCKED branches.
