DUPLICATED CORE ABILITIES
The Core Rules describe dozens of abilities, including weapon abilities and deployment abilities. These are referred to as Core abilities, and most models, units, weapons or attacks either have one or more of them innately, or can gain them during the battle through other means such as Stratagems, Enhancements or attached Leaders. Regardless of the source, if a model, unit, weapon or attack has multiple instances of the same Core ability, those abilities are not cumulative, and only one instance of that ability can take effect at any one time. If that ability has a number after it (e.g. [SUSTAINED HITS 1], Scouts 6"), the controlling player must choose which instance of that ability to apply each time. Note that multiple instances of the [ANTI-] ability are only considered to be the same if the keyword listed after the word ‘Anti’ is the same (e.g. [ANTI-VEHICLE 4+] and [ANTIVEHICLE 3+] are considered to be the same ability, but [ANTI-VEHICLE 4+] and [ANTI-INFANTRY 2+] are not).
