I am creating user files for the Dragonlance Spectre of Sorrows adventure campaign. Currently I am working on chapter 4 of book 2 (Spectre of Sorrows) and am having trouble with the animated object called the celestinfernal engine. The idea behind the object is that a gnome made the clocktower engine keep itself in balance by giving it celestial and fiendish traits. It is a colossal construct with a template similar to the celestial template. The "balance" it was supposed to create has gone haywire (as any gnomish invention does) and it is now more of a chaotic template. I've included the statblock on the creature. Currently I am having trouble adding the "Smite Law" ability to the creature. Any suggestions?
