Hirelings and warbands can improve in the same way that your player mice do.

• Hirelings who receive a share of treasure gain 1 XP per pip they are given above their daily wage.
• Warbands who receive share of treasure will gain 1 XP per 10 pips they are given above their weekly wage.

Hirelings and warbands advance at the same rate as player mice, so once they get 1000 XP, they advance to Level 2.

Not receiving a share of treasure may cause resentment amongst hirelings.
