Minion Levels and Slots
Minions level from +0 to +10, each of their passives and abilities is upgraded on its own, and two slots add a minion equipment piece and a skill inherited from another minion.
Levels
Only the active minion gains XP: 1 XP for each kill that gives your hero XP. +10 is the top level (204,036 XP from +0); at +10 it gains no more XP.
| Level | XP to reach it |
|---|---|
| +1 | 300 |
| +2 | 570 |
| +3 | 1,083 |
| +4 | 2,058 |
| +5 | 3,910 |
| +6 | 7,428 |
| +7 | 14,114 |
| +8 | 26,816 |
| +9 | 50,951 |
| +10 | 96,806 |
Skill upgrades
Each passive and ability of a minion has its own level, from +0 up to the minion's own level. Upgrading a skill by one level costs gold by the minion's rarity and two materials by its species; the upgrades to +5 and +10 also take 1 Rein of that minion (not for the Oakback Pack Bull). A passive's value and an ability's numbers grow with its level; each minion's page shows them at +0 and +10. Outside town the Minions window says: "Can only level up in town or the training grounds".
