Given how far they have gone on the yard to investigate the cauldron, yes I would say Piro is in that range and able to cast it just fine. They are all within 60 feet, but Piro and Jin moved up the farthest I believe, so closest to the old man. Thankfully, the check for the area's magic was done before moving so they didn't step in the midst of those cages.<br/><br/>Suffice to say, without any such checking, and without wording about how they go about, it might have lead to a fight rather quickly.
