Spreadsheet ratings

Bannerlord v1.4.8 · checked 2026-11-10 · updated 2026-11-11

The wanderer ratings of the author's workbook compendium/wanderers.xlsx. They are spreadsheet heuristics, not game rules: no game model computes or reads them, so no official module overrides them. For how the game builds a wanderer, see Wanderer generation; for a plain-language version, see the companions guide.

The ratings are computed by src/bannerlord/wanderers/ratings.py and written to the native_* and naval_* columns of data/wanderers/templates.csv.

Rulesets

These are the formulas of Table19 in compendium/wanderers.xlsx, ported as written and computed on template skills (before noise). Each one is calculated under two rulesets:

Prefix Skills Templates (max(All) taken over)
native_ 18 core skills 67 default; naval rows are blank
naval_ 18 core + Mariner, Boatswain, Shipmaster as a 7th group naval all 78

The native_ values match the workbook's cached results exactly. Default templates have no naval skills, and no naval template has a larger All than 1495. So default templates score the same under both rulesets, and only the 11 naval templates get new scores. Naval skills raise All, which lowers the other group scores; they add to no role metric.

Formulas

Symbols:

Column (after prefix) Formula
sum_<group> sum of the group's skills (VIG, CTR, END, CNG, SOC, INT, and naval)
sum_all sum of all skills in the ruleset (All)
score_<group> sum_<group> / All
approx_level All / max(All)
melee_naive score_vigor + score_endurance
melee_ath (VIG + Athletics + Crafting) / All
party_leader_naive score_social + score_intelligence
archer_naive (Bow + Athletics) / All
archer_attrs (CTR + END) / All
warrior (VIG + CTR + END) / All + (1 − approx_level)

Worked example, naval_party_leader_naive of the Scholar (spc_wanderer_empire_0):

  1. SOC = Charm 110 + Trade 45 + Leadership 50 = 205.
  2. INT = Steward 120 + Medicine 90 + Engineering 130 = 340.
  3. All = 820.
  4. score_social + score_intelligence = 205 / 820 + 340 / 820 = 545 / 820 = 0.6646.

Top five per rating

The guide ranks templates by four naval_ columns: Warrior is warrior, Melee fighter is melee_ath, Archer is archer_attrs, Party leader is party_leader_naive.

These are spreadsheet heuristics from the author's wanderers.xlsx, not game rules.

Warrior: the share of all skills held in vigor, control and endurance skills, plus 1 minus the wanderer's skill total divided by the highest skill total of any template.
