Board Pity Calculator

The calculator only needs two things, and picking the wrong one for either quietly throws off both numbers it gives back.

• Which system you're tracking — the Character board and Arc Research run on separate counters with separate hard-pity turns (90 vs 80), so a Character-board count typed into the Arc Research field produces a guarantee estimate that's simply wrong.
• Turns since your last S-Class, not your total rolls ever made — every S-Class landing resets this counter back to zero on its own board, so what matters is the streak since the last one, not a lifetime count.
• Optionally, how many Dice (or Tri-Keys, for Arc Research) you're holding or planning to spend — this turns the odds into a rolls-remaining estimate instead of a single-roll percentage.

The Character board runs two overlapping thresholds, and the calculator's job is to tell you which zone your count sits in.

• Before turn 70, every roll carries the same low starting odds for an S-Class landing.
• From turn 70 onward (soft pity), the board's own odds step up sharply for every roll that still doesn't land an S — this is why the calculator's percentage climbs fast once you cross that line instead of moving in small steps.
• At turn 90 (hard pity), the board guarantees an S-Class no matter what — landing one before that resets the counter to zero.
• Arc Research runs a single hard-pity line at turn 80 instead of two thresholds, and its base odds already start higher than the Character board's — so its ramp to guarantee is more front-loaded.

Two facts the calculator assumes, and both are worth spelling out because habits from other pull-based games get them backwards.

• Landing an S-Class on a limited board is 100% the featured character — there's no coin-flip step afterward, so the calculator's guarantee count is the actual number of rolls to the character you want, not just to any S-Class.
• Pity carries over between every limited Character board released so far — switching to a newer board keeps the same counter instead of restarting it. Arc Research pity works the same way between its own Limited Issues, and additionally accumulates permanently rather than resetting on any schedule.
• One thing pity is not: separate cosmetic-reward milestones some boards hand out around specific roll counts are tracked on their own and don't carry between boards the way pity does — don't confuse the two when reading a board's own reward list.

The zones above describe shape, not size — here are the actual percentages behind them, pulled straight from the game's own drop tables.

• Before turn 70 on the Character board, a single roll's S-Class odds sit at a flat 0.99% Baseline; averaged across a full cycle including every pity step, the blended S-Class rate works out to roughly 1.87% per roll.
• From turn 70 onward, the board's Modified state pushes that same per-roll odds up to roughly 19.59% — a jump of nearly 20x over Baseline, which is why a streak that crosses turn 70 tends to resolve fast.
• Arc Research runs its own separate curve: a flat 3.00% base S-Arc rate pre-pity, blending to about 4.19% once pity is folded in, with its hard guarantee sitting at turn 80 rather than 90.
• Mid-tier rolls aren't wasted turns either — the Character board's A-Class rate runs 22.98% per roll (roughly 11.67% toward a character-flavored reward, 11.31% toward an Arc-flavored one), while Arc Research's own A-tier sits at 7% base / around 13.47% blended, with B-tier filling most of the remainder on both systems.

None of these numbers move depending on which specific board or Limited Issue is currently live — they're systemic constants, not per-banner values.

This calculator's Arc Research mode tells you when an S-Arc is guaranteed, but it doesn't distinguish between "any S-Arc" and "the specific featured weapon" — worth spelling out separately because the two arrive on different schedules.

• Arc Research only accepts multi-rolls, never singles, so its whole structure counts in blocks of rolls rather than one at a time.
• Any S-Arc is guaranteed well before the featured one is: the guarantee for landing some S-Arc lands earlier in the sequence, while the guarantee for the specific featured weapon sits at this page's hard-pity turn.
• Land an S-Arc before that later point and it isn't automatically the featured piece the way an S-Class always is on the Character board — there's a real, non-zero chance it's a different S-Arc instead. Only once you reach the hard-pity turn does the featured weapon itself become guaranteed.

Practical read: if you only want "an" S-Arc for the loadout slot, you can stop earlier than this page's guarantee turn. If you want the specific featured weapon, the calculator's rolls-remaining number for Arc Research is the one to trust.

Everything above covers the Limited Character board and Arc Research. NTE also runs a permanent Standard board (its own currency, its own Fabricated Dice), and it works on a different kind of guarantee that this pity calculator was never built to track.

• The Standard board carries a one-time guarantee: reach its fixed roll threshold and you get to freely pick one character from its starter S-Class roster, rather than receiving a random one.
• That guarantee doesn't expire and doesn't need to be claimed the moment it unlocks — it sits banked until you choose to use it, so it's possible to hold off if you're only missing one specific starter and would rather wait than spend the pick early.
• Because this is a pick-your-own reward rather than a rate-up mechanic, it doesn't interact with the Character board or Arc Research counters at all — rolling on Standard doesn't add or subtract from either Limited pity track.

If your question is "how close am I to my next guaranteed Limited pull," this calculator has the answer. If it's "how close am I to the free starter pick," that's a separate, one-time milestone tracked entirely inside the Standard board itself.
