Phil takes the lead, carefully picking the way through the rough ground. At the glimpse of someone hiding beyond them he stops, holding his hand up with a fist to indicate they should stop. Silently he points in the direction of the figure and then places a finger to his lips to indicate they should be quiet. Then he begins sneaking in that direction, eyes peeled for any sign of human(oid) life.

Perception +5, Stealth +2, Survival +5. Philemon would be using all three to try and approach, eyes open for any immediate movement, looking at trail signs for indications that someone(thing) has been this way, and trying to do it all quietly. If you want dice rolls: Perception (1d20+5)[13], Stealth (1d20+2)[6], and Survival (1d20+5)[23]
