Dragonfire Strike

Type of Feat: Draconic
Prerequisite: Cha 11, Dragonblood subtype*, and sneak attack/skirmish; or Hand of the Winged Masters 3

When you perform a sneak attack or skirmish, if this feat is activated, your sneak attack or skirmish damage is the element related to your draconic ancestry. If that dragon type is not associated with one of the 5 main elements, the damage type is fire. If you apply this effect, increase the extra damage dealt by ld6 points.

You can take this feat if you do not have sneak attack or skirmish, but it will do nothing until you do.

Also note that due to engine limitations the sneak attack implementation is a bit iffy, and may not always behave as expected.
Use: Selected.

*Note: In addition to race, you can gain the dragonblood subtype through the Dragon Devotee or Dragon Disciple classes, or through the Dragontouched or Dragon Heritage feats. If you take this feat and are not dragonblooded or a Hand of the Winged Masters, you will be deleveled or unable to level.
