This is the third step of using an action during a model's activation
All offensive actions require an offense roll.
Support actions never require an offense roll unless the action indicates otherwise. If no offense roll is indicated, skip directly to Resolve Effects.
If the support action does require an offense and defense roll, the action will specify which attributes are used.
A model´s attributes and offense roll can be increased or decreased by equipment, potions, and other game effects. A model must include all of these effects when making its offense roll.
