Sorry if necro-ing this is an issue but uh, I'm gonna throw my hat in with some rogue modron moves:
Bard: When you use Discern Realities to examine a mechanical device, you can ask the GM to inform you how precisely that object functions (or doesn't function) as well as any methods of sabotage or repair.
Cleric: Because of your own nature as mechanical AND organic, you may repair devices with healing spells.
Fighter: Your ability to calculate battle situations has granted you a unique advantage, you can line enemies up perfectly which allows you to split your damage between two enemies with Hack and Slash.
Thief: When you try to talk your way out of a situation with law enforcement, take a +1 due to your attunement with the law.
Wizard: You are capable of thinking fast enough to construct a more effective arcane barrier from an ongoing spell (as per Spell Defense,) allowing you to subtract 1+the spell level from damage instead of just the spell level.
Any ideas? Criticisms? I know fighter and wizard are kind of janky.
