Heroes 3 secondary skill chance calculator

When a hero gains a level, the game raises one primary skill and opens the level-up window with two secondary skills to choose from, usually one the hero already has, a level higher, and a new one; it shows nothing of later levels. Loading a save from before the level-up brings back the same two skills: the hero record holds a seed set when the map started, and the offers follow from that seed and the new level.

The class decides how often each skill comes up; Wisdom is offered once 6 levels have passed since it was last offered (3 for a magic class), and a magic school (Fire Magic, Air Magic, Water Magic, and Earth Magic) after 4 levels (3 for a magic class); a hero with eight skills is offered only upgrades. Pick the skills you take level by level to plan a hero, or state the two skills the game offered to find your hero's seed and see every later offer exactly.
