Gets Hot When firing a weapon that Gets Hot, roll To Hit as normal. For each To Hit roll of 1, the firing model immediately suffers a Wound (armour or invulnerable saves can be taken) - this Wound cannot be allocated to any other model in the unit. A character cannot make a Look Out, Sir attempt to avoid a Wound caused by the Gets Hot special rule. A vehicle instead rolls a D6 for each roll of a 1 to hit. On a roll of a 1, 2 or 3 it suffers a glancing hit.
Weapons that do not roll To Hit (such as Blast weapons) must roll a D6 for each shot immediately before firing. On a 2+, the shot is resolved as normal. For each roll of a 1, the weapon Gets Hot; that shot is not fired and the firing model immediately suffers a single Wound (armour saves or invulnerable saves can be taken) - this Wound cannot be allocated to any other model in the unit. A character cannot make a Look Out, Sir attempt to avoid a Wound caused by the Gets Hot special rule. A vehicle instead suffers a glancing hit on a further roll of a 1, 2 or 3.
If a model has the ability to re-roll its rolls To Hit (including because of BS6+ or the Twin-linked special rule), a Wound is only suffered if the To Hit re-roll is also a 1; it may also re-roll Gets Hot results of 1 for weapons that do not roll To Hit.
