Borer

When rolling damage for a weapon with Borer, roll a number of damage dice equal to the HP value of the eligible model that damage is being assigned to, up to a maximum of 6 dice per successful Target Lock.

If damage has not yet been assigned to a specific model, use the HP value of the closest eligible model that would receive that damage under core/damage_allocation.md.

Borer changes the number of damage dice rolled. It does not change Target Limit, damage allocation, Sustained Damage, Critical Damage, or model removal timing unless another rule explicitly states otherwise.
