The Pilgrim is a low level non-kingdom troop. They have better stats and equipment than the farmer and peasant woman while asking for the same minimum wage of 1 denar. Despite this, they will never carry a shield, thus being susceptible to ranged attacks and cavalry charges.
They can't be recruited, but are often common sights in prisoner stacks where they can be recruited from.
This troop upgrades to Monk for 10d.
