Asurmen

When determining Warlord Traits of Asurmen, he always has D3 traits from the Warlord Traits table in Codex: Craftworlds (pg 148) - re-roll any duplicates.

Asurmen has a 4+ invulnerable save. This is increased to a 3+ invulnerable save whilst he is fighting in a challenge.

A model with this special rule has the Hatred special rule against Daemons of Slaanesh or models with the Mark of Slaanesh. Furthermore, when making Fear tests, a unit containing at least one model with this special rule suffers a -1 penalty to its Leadership if it is engaged in combat with a unit that contains at least one model with the Mark of Slaanesh or the Daemon of Slaanesh special rule.

A unit comprised entirely of models with the Battle Focus special rule can either shoot and then Run, or Run and then shoot, in the same Shooting phase. The unit must complete both actions before you move onto the next unit - otherwise the chance to make the second action is forfeit.

A model cannot Run if it fired a Heavy weapon during the same Shooting phase unless it has the Relentless special rule. Similarly, a model that has Run cannot then fire a Heavy weapon in the same Shooting phase unless it has the Relentless special rule. Models that cannot Run gain no benefit from the Battle Focus special rule.

If a unit contains at least one model with this special rule, and that unit is charged, every model with the Counter-attack special rule in the unit gets +1 Attack until the end of the phase.

If, when charged, the unit was already locked in combat, the Counter-attack special rule has no effect.

When chosen as the target of a charge, a unit that consists entirely of models with this special rule can either choose to fire Overwatch at BS2, or gain the Counter-attack and Stubborn special rules until the end of the phase (in which case it cannot fire Overwatch).

If a model with this special rule suffers an unsaved Wound from an attack that inflicts Instant Death, it only reduces its Wounds by 1, instead of automatically reducing its Wounds to 0.

Units containing one or more models with the Fearless special rule automatically pass Pinning, Fear, Regroup tests and Morale checks, but cannot Go to Ground and cannot choose to fail a Morale check due to the Our Weapons Are Useless rule. If a unit has Gone to Ground and then gains the Fearless special rule, all the effects of Go to Ground are immediately cancelled.

A unit composed entirely of models with this special rule can re-roll one or more of the dice when determining Run moves and charge ranges (such as a single D6 from a charge range roll, for example).

Independent characters can join other units.  They cannot, however, join units that contain vehicles or Monstrous Creatures.  They can join other Independent Characters, though, to form a powerful multi-character unit!  Independent Characters pass Look Out, Sir rolls on a 2+. A unit that contains one or more Independent Characters does not need a double 1 to Regroup if reduced to below 25% of its starting numbres, but instead tests as if it had at least 25% remaining.
