Fire Affinity (Fire Pad). When you deal fire damage for an effect that is not a spell or attack you can roll double the damage dice. In addition, when you produce a fire effect that is not a spell but does have an area of effect you can control the shape of the area. You can decide if the area is a Cone, Cylinder, Line, Sphere, or Square. Changing the area's shape may change its total size, but cannot change its range. For example a 15ft. cone is significantly smaller than a 15ft sphere.

Lightning Affinity (Lightning Pad). When you deal lighting damage for an effect that is not a spell or attack you can roll double the damage dice. In addition, when you take the dash action you can pass through the spaces of other creatures without their permission. While dashing you do not draw opportunity attacks and deal 2d6 lightning damage to any creature whose space you move through. This damage is not doubled by the first part of this effect, and a creature cannot take this damage more than once per turn.

Necrotic Affinity (Corpseblossom). When you deal necrotic damage for an effect that is not a spell or attack you can roll double the damage dice. In addition, you can use acrobatics to make checks related to grappling, and creatures grappled by you take 2d4 necrotic damage at the start of their turn. This damage is not doubled by the first part of this effect.
