Can choose to apply at start of any friendly Movement phase, once released it cannot be bound back during the battle:

Gains Frenzy (+1 A and Immune to Psychology)
Gains +1 WS, +1 S, +1 T, +1 I, +1 Ld
Each time Malus makes a To Hit roll of 1, a friendly model in base contact (of your choice) suffer an automatic hit at Malus's Stength that must be re-rolled if it fails to Wound

Cold Ones (including Spite) in the Unit are not afffected by Stupidity

Unit always strikes first
If the unit's Initiative is equal to or higher than the enemy's, he can re-roll failed misses when striking in close combat.

A model with this speical rule has the Hatred special rule. In addition, its Hatred applies in every round of close combat, not just the first.

At the start of each Close Combat round, a unit that is in base contact with one or more enemy models that cause Fear must take a Leadership test, before any blows are struck.

Models with this special rule (but not their mounts) re-roll all To Wound rolls of a 1 when making close combat attacks.

A model riding a cold one reseives an armour save bonus of +2, rather than the usual +1 for cavalry mounts.
