Q: If a rule or ability grants a re-roll on, for example, ‘hit rolls of 1’ (such as a Space Marine Captain’s Rites of Battle ability) does that effect trigger before or after applying modifiers to the hit rolls?A: Re-rolls always happen before modifiers, so the re-roll ability is triggered before applying modifiers.For example, let’s imagine a Space Marine (Ballistic Skill 3+) moves and fires a heavy bolter (a Heavy 3 weapon) whilst within range of a Space Marine Captain’s Rites of Battle ability (allowing you to re-roll hit rolls of 1).The hit dice are rolled and result in a 1, 2 and 5.Re-rolls are applied before modifiers. In this example a single dice is re-rolled because of the Captain’s ability, this time resulting in a 3.Modifiers are applied after re-rolls. In this example there is a -1 modifier to the hit rolls for moving and firing a Heavy weapon. That means that the post-re-roll scores of 2, 3 and 5 are modified to 1, 2 and 4. Comparing the final results to the model’s Ballistic Skill, only one shot hits the target.
