Suddenly, you all hear the thudding of what seems to be giant footsteps from some kind of heavy, and very big creature, however, your able to tell from the sound that if you were to hide, you would have some time to do so. 

Balasar

Balasar will try and hide.

Make a stealth check, Balasar

With advantage

Jetsam loads his crossbow and attempts to hide as well. 19

In the game log.

Rizo tries to hide like his companions to get the jump on whatever is that huge creature that is approaching (Stealth: 17)

You all succeed at hiding, except Rizo. As you all begin to hide, the stomping suddenly grows closer, and a large Stone Golem comes rumbling into view, and it turns to Rizo, who wasn't able to hide in time, and gives Rizo a chilling, expressionless stare. What do the lot of you do?

Balasar

Balasar thinks, "What would Master Ko-Chi do at a time like this as he looks the golem over in awe."

Balasar makes no moves and waits to see if the golem attacks or not.

Action:  Ready (If the Golem attacks Rizo, then Balasar Attacks the Golem.)

Cast Guiding Bolt!  at the Golem:  14!  Damage:  12

Rizo steps one step closer to the Stone Golem, slams his staff into the ground and casts Shillelagh. He menacingly glares at the Stone Golem and yells, "You shall not pass!" before preparing to dodge the incoming attack and providing cover for his companions. 

The stone statue simply looks at Rizo, expressionless. It simply stands there. Staring into Rizo

Tommy whispers to Jerry.

"Go and distract that thing so Rizo can get out of there"

Jerry will run and and try to distract the golem.

Jerry will run in and use its movement to run circles around the golem.

Tommy will prep an arrow to shoot the golem 

Jetsam fires his crossbow at the golem, glad he loaded a +1 bolt in. Attack: 12 Damage: 12

 As Jerry begins to run around the Stone Golem, the stone giant looks at the bobcat, clearly wondering what the cat is doing

Quote from Smoke_and_Oakum >>

Jetsam fires his crossbow at the golem, glad he loaded a +1 bolt in. Attack: 12 Damage: 12

 Jetsam, as you fire the arrow at the Golem, it chips off it's stone head harmlessly, but now due to your attack, the Stone Golem has clearly taken this as a act of aggression, and turns towards Jetsam, and starts stomping towards him. Everyone roll initiative!

Does Rizo get an attack of opportunity?

Ini: 18

Yes you do, but whether you do that you had better take it into serious consideration. This fight will definately not be easy."

Rizo swings his staff at the leg of the passing golem.
