Scout’s Warning [free-action] (Feat 4)
Rogue

Trigger You are about to roll a Perception, Stealth, or Survival check for Initiative.

You visually or audibly warn your allies of danger, granting them each a +1 circumstance bonus to their Initiative rolls, or a +2 circumstance bonus if you’re using the Scout Exploration activity. Depending on whether you use gestures or call out, this action gains either the Visual or the Auditory trait, respectively.
