SFS Standard Momentum [one-action] Feat 8

Source Player Core pg. 147
Requirements Your last action was a successful solar weapon Strike.
You use the momentum of your last attack to maneuver around the battlefield, either by leaving photonic images or making great gravity-assisted leaps. Step twice.

Graviton-Attuned You move 10 feet with each Step, rather than 5 feet.

Photon-Attuned You leave an afterimage in the square you started in. This image lasts until the end of your next turn but ends early if another creature enters the space. This afterimage counts as an ally to you and your allies for the purposes of flanking.

Traits

Attuned:You can't use abilities with the attuned trait while you're unattuned. Many attuned abilities require you to be specifically graviton-attuned or photon-attuned, while others can grant additional benefits based on your current stellar attunement.
Flourish:Actions with the flourish trait are special techniques that require too much exertion for you to perform frequently. You can only use one action with the flourish trait per round.
