Can I string the Dimensional Agility Feat chain (specifically, Dimensional Savant) and Precise Strike feat together? As I read it since I can flank with myself as an ally doesn't the feat bonus apply as well?
Whenever you and an ally who also has this feat are flanking the same the creature, you deal an additional 1d6 points of precision damage with each successful melee attack. This bonus damage stacks with other sources of precision damage, such as sneak attack. This bonus damage is not multiplied on a critical hit.
While using the Dimensional Dervish feat, you provide flanking from all squares you attack from. Flanking starts from the moment you make an attack until the start of your next turn. You can effectively flank with yourself and with multiple allies when using this feat.
