How to stop companions levelling up?

[iron_commander]

May I know if its possible to stop my companions (alayen etc.) from levelling up further? As i like them at their present levels and I do not want to pay them more upkeep per week , which scales with their levels?

Why don't you change the XP multiplier for heroes to zero in module.ini (of the mod you play) and see what happens?

hero_xp_multiplier = 0.0;

Haven't tried it myself, so I don't know if this works or not.
