Franklin cannot tell the extent of Maloof's injuries, and therefore continues with his plan: "Aim high so you don't hit Maloof in the back," he instructs Balbo and Drogo. (accepting the -4 penalty)

Nailus will jump into the fray.

Assuming color spray will not affect a statue, he could hit it with a wand of fire or cold. He would choose cold assuming it might make stone more brittle, But would not want to hit Maloof.
If there is a chance that will happen he will instead attack with battle axe and shield.
