The Paymaster may be accompanied by a Paychest guarded by two Paychest Bodyguards which increases his Unit Strength by 2. This can be represented by either modelling the Paymaster with the Paychest and guards on a single base, or as a separate model placed in base contact with the Paymaster at all times (it may be placed in the second rank of a unit if you wish). The Paychest increases the radius of the Paymaster's "Hold Your Ground" by 6".
If the Paymaster is killed, all friendly units gain Hatred against the enemy unit or model that killed the Paymaster.
