Rules and numbers

  1. confirmed Success = 70% (SUCCESS_BASE) +1% per level above the activity's requirement +1% per action source, capped at 100%.success% = min(100, 70 + max(0, level - reqLevel) + sources)
    Source: Constants.js:103-111
  2. confirmed Success sources = cape/pet sources + owned tools (skill + lanterns) + Fortress Banners/Ledgers + Sure Beacons + Collector progress x 10 + Fortify Steady Hands talent.sources = capePet + tools + milestones + sureBeacons + collectorProgress*10 + talentSuccessPct
    Source: ClientState.js:2533-2540
  3. confirmed Every 1% of raw (uncapped) success above 100 removes 0.05 s from the action (SUCCESS_OVERFLOW_SPEED_PER_PCT).overflowSec = max(0, rawSuccess - 100) * 0.05
    Source: Constants.js:121-128

    Source: Constants.js:119-120; LoginScreen.js:205 (patch note)
