Rogue Trader 2015: Halcyon Rising
A character suffers Damage from fire each Round he is exposed to it. At the beginning of each Round after the first in which a character is exposed to the same source of flames (or if he is hit by a weapon with the Flame special quality or suffers certain Toxic Critical Effects), he must make a Challenging
(+0) Agility Test or catch on fire.
Once a character is on fire, he suffers 1d10 Damage (with no reduction from armour) and takes 1 level of Fatigue each Round until the fi e is extinguished. All Damage from fire is treated as Energy Damage for the purpose of determining Critical Effects—if the location is not otherwise specified, use the body location. While on fire, a character must make a Challenging (+0) Willpower Test at the beginning of each of his Turns in order to be able to take Actions normally; otherwise, he may only run around and scream, which counts as a Full Action. A character that is on fire may try to extinguish the flames himself by dropping prone and making a Hard (–20) Agility Test, which counts as a Full Action. The GM can make this test easier or harder depending on environmental conditions and whether the blazing character is able to receive any help from nearby allies.
