Training calculator

How to use it

1. Pick the hero's race and age. Race decides the career window, so the same age means different things for a Human and an Elf.
2. Enter current and potential ability. If you only see stars, multiply by 40: a 3★ hero is about 120.
3. Set Veterancy and switch on any learning traits the hero has.
4. Describe your yard and the mentor you plan to assign, then read the three numbers at the top and the levers underneath.

The training formula

Each six-day settlement, a hero on Train gains ability equal to the product of these terms. The game rounds the result down and rolls the fraction as a chance of one more point, so over time the average is exactly the product:

• Base 3.
• Teaching: 1.6 with no mentor. With a mentor, 2.4 × their teaching quality × class fit, but never below 1.6, so a poor mentor never hurts.
• Yard: 1 + 0.15 per Training Ground level (+0.25 more for Master's Yard), multiplied by your trainer's bonus of up to +60% at skill 100.
• Life stage: ×1.4 while Greenhorn or Rising, ×0.5 in Twilight, otherwise ×1.
• Veterancy and traits: up to +25% from Veterancy 1 to 20, ×1.1 each for Diligent and Professional, and Late Bloomer's ×0.8 early, ×1.25 later.
• Room to grow: full speed while the gap to the cap is at least 60% of the cap; after that it falls with the square of the remaining gap, to a floor of 6%.
• 6/7, because the old weekly amounts now settle every six days.

Why growth slows down

Three separate things cap a hero, and the calculator shows which one is binding right now:

• The approach to the cap. The last stretch is slow. A hero with only a quarter of their cap left to gain trains at about a sixth of full speed.
• The age cap. Before their peak years a hero cannot exceed part of their potential: about 57% at the start of the career, rising to 100% at peak.
• The fade. Once past their best, the cap slides down toward 72% of potential by the end of the career. Well-Preserved delays the slide.

Life stage matters too. Greenhorn and Rising heroes learn 40% faster, and Twilight heroes at half speed, which is why young prospects are worth putting in the yard early.

Typical timing by race

Each hero's peak is a hidden roll centred on their race's average, give or take about a tenth of the career. The calculator uses the average unless you pick early or late. Past their peak, older mentors teach better, by up to 25% × the race's teaching modifier.

Choosing a mentor

Teaching quality comes from the mentor's Veterancy (0.73 to 1.3), Leadership (0.78 to 1.25), age, and trait: Born Mentor ×1.2 or Exacting ×1.18 with added stress. Then class fit multiplies it:

Bad blood cuts it: a grudge against the pupil's old hall halves the fit, and a personal grudge between the two means the mentor teaches nothing at all. A mentored Rising or Greenhorn pupil can also, now and then, gain a point of potential, which this calculator does not count.

What the calculator assumes

• The hero trains every cycle and their Veterancy stays where you set it. In practice delves raise it, which makes later cycles a little faster.
• Two hidden values are average: Adaptability (10) and the peak roll. Real heroes vary around the projection.
• Hone, rehearsal and passive Training Ground growth are separate and not included. See the training guide for how they fit together, and hero state for ability and stars.
