"I cannot pick a lock." Randy says in monotone.

Randy, having an initiative of +2, decides to shoot a Fire Bolt at the window.

Randy, make a spell attack against the glass window.

Attack = 9

Damage = 1

Randy: Your Fire Bolt shatters the window and the sound of broken glass echos down the lane. Lucky due to the damp sea air, the the warehouse doesn't catch fire.

What's next?

Randy looks into the warehouse through the destroyed window.

Randy: Make a Perception check.

Randy's perception = 7

Randy: From where you're standing you can't see much, but what you see isn't pretty. The interior of the warehouse is a mess, tables and chairs have been carelessly tossed across the floor.

Looking through the window Randy says, "The interior of the warehouse is a mess, tables and chairs have been carelessly tossed across the floor. I don't see any people."

"Stand back my fair friends!"  Dewey exclaims as he arrogantly flips his collar up, and smooths back his whiskers. 

He dives through the window.  

"I don't think that-" Sol begins but trails off as Dewey dives in.

Sol turns and scans the alley one more time, seeing if the commotion had caused anyone to stir.

 Kevin steps up to the window Dewey has just flailed himself through and takes a look around.

Perception roll:

23

Dewey: Make an Acrobatics check to see if you cut yourself when you leap through the broken window.

Sol Rhea: There is no reaction on the street from the sound of breaking glass. Either there is no one there, or they're used to the sound of broken glass on this street.

Kevin: You stick your head through window and look around, and you're able to see a lot more than Randy.  Beyond the fallen furniture are the corpses of a dozen men. They lay along the walls, their rapiers and daggers lying nearby.

Acrobatics = 24

When I land I look around the room for any threats and report back to the party.  Perception = 4

So looks like I botched my Acrobatics check when I leaped through the window, even though I have a ******* +5 in Acrobatics.

Rolling a d100 = 49

Randy looks at Dewey, and yells into his mind, "LET US IN!! OPEN A DOOR!!!"

Dewey: The way you haphazardly jumped through the broken window causes you to cut yourself on some glass and you take 4 points of damage.

(No d100 needed, that's only for botched attack rolls)

Now that you're in the room, you get a better look around. You see the fallen chairs and tables, the pile of dead men and the pile of weapons. On the north side of the warehouse, you see stairs rise to an open level above.

Staunching the blood and making sure no one saw, Dewey sweeps open the front door. 

“There be a perfect cat’s landing on my feet. And I have secured the room from any dangers for me mates.”

Randy walks into the warehouse and his hood dips with a nod towards Dewey. "Let us see if any of the bodies belonged to the people we seek." Randy starts examining the corpses to see if any of them match the descriptions of people for whom they were looking.
