In Heroes of Might and Magic: Olden Era, Arena players choose a hero and build an army before fighting. Skills arrive through three-choice offers. If your build needs a particular set of skills, which faction gives you better odds?
For the five skills below, Grove and Hive tie for the highest mage baseline: 46.46% per ordinary new-skill draw. This measures access to a chosen skill set, not faction win rate. The five choices are a player preference, not a claim that these are universally the best skills.

Figure 1. Compare the same draw event for every class; do not mix new-skill draws with upgrade offers.
1. Mages
The highlighted skills are Thaumaturgy (奇术), Sorcery (秘术), Resistance (抗性), Primal Magic (原始魔法), and Battle Magic (战斗魔法). Older reference translations may call Sorcery 巫术, Resistance 抵抗术, and Primal Magic 原初魔法.
These are class baselines, before learning any ordinary skill and without an individual hero’s weight override. The event is one draw from the ordinary new-skill pool—not “appears somewhere in three cards” or “learned by level 10.”
Formula & scope / 公式与口径
Single-draw chance = selected skill weight ÷ total eligible weight. Combined chance = sum of the five selected weights ÷ the same total. Filtering does not change the pool, denominator, or all-six ranking.

Grove and Hive have the same rates for all five. Their Primal Magic rate is twice Temple’s, while their other four rates match Temple’s. Necropolis ranks above Dungeon despite a lower Primal rate: Leadership has zero weight in its pool, so its eligible denominator is smaller. Schism offers Resistance more often than any other mage class here, but ranks last when all five count equally.
2. Warriors
Warriors use different class weights, so they belong in a separate comparison. Thaumaturgy has zero weight in their ordinary new-skill pool, so the warrior table shows only Sorcery, Resistance, Primal Magic, and Battle Magic. Its combined rate adds those four skills; dropping the zero column does not change the ranking or denominator.
Formula & scope / 公式与口径
Single-draw chance = selected skill weight ÷ total eligible weight. Combined chance = sum of the four selected weights ÷ the same total. Filtering does not change the pool, denominator, or all-six ranking.

Schism leads this particular warrior comparison. Its Sorcery and Battle Magic rates outweigh its lower Resistance and Primal rates. That does not establish the best warrior build: a different target skill set could reverse the ranking.
3. What the numbers mean
A weight is a relative share of a pool, not a percentage. For a baseline Grove mage, the five weights are 150 + 225 + 75 + 80 + 225 = 755. All eligible ordinary new skills have total weight 1625. The combined chance is therefore 755 / 1625 = 46.46%. A single draw can return only one skill, so adding these five shares is valid. Totals are calculated before rounding; exact ties share a rank, with the next rank skipped.
Do not multiply this total by three or use 1 − (1 − p)³ for an Arena offer.
The cards cannot repeat a skill, upgrades use a separate pool, and the middle
card has a special magic-school branch at hero levels 4 and 8. Once a skill is
learned, it leaves the new-skill pool and can instead appear as an upgrade.
Individual heroes matter too. In the reviewed build, 15 Arena heroes have
effective new-skill weight overrides at levels 2, 4, and 6. For example, Hive
hero 席尔 (demon_hero_11) changes Resistance from 75/1625 to 500/2050 before ordinary
skills have been learned. Its five-skill total becomes 1180/2050 = 57.56%
at those levels. A shared faction table is not a promise that every hero is identical.
Version and source
The source catalog was reviewed on September 3, 2026, against commercial version 0.80.48 / Steam build 24970573. On September 6, 2026, a fresh read-only audit of the complete 0.80.49 / build 25061458 installation rechecked every normalized field in the twelve Arena class tables, all 77 hero bindings, 28 replacement records, and 30 skill definitions. They were unchanged, so the probabilities below apply to both reviewed builds.
The source is the installed Core.zip: DB/arenaGame.json binds the heroes
to the twelve arenaGame_*_skills_table.json files under
DB/heroes_skills/skills_by_level_tables/. Hero exceptions come from
DB/heroes_skills/skills_by_level_replace_tables/skills_by_level_replace_table.json;
Chinese names come from Lang/zhCN/texts/heroSkills.json.
The read-only audits checked all twelve tables and all 77 Arena hero bindings.
The percentages are arithmetic from those weights, not measured playtest frequencies.
There are public sources to compare against, but their modes differ. The official community wiki’s skill-roll index separates twelve ordinary tables from twelve Arena tables. HeroWorld’s hero-class page contains ordinary-mode weights; its Arena page describes the draft rules. Those ordinary class numbers must not replace the installed Arena-specific tables used here. Public pages may also describe a different build.
This page keeps only a small, versioned excerpt for the selected-skill comparison. It does not distribute the game archive, artwork, or copied skill descriptions. The local checker compares that excerpt with the project’s shared Game Knowledge API; neither the Reference App nor the Simulator is used to prove the game data.
This is an unofficial player analysis, not an official game guide.
Takeaway: for this five-skill target, start with Grove/Hive among mage baselines and Schism among warrior baselines. Then check the actual hero and what you have already picked before treating the table as draft advice.
