Surreptitious Casting

Requirements- Relevant skill

You may cast spells, drink potions, use Spirit Scripted frags, and Artificer devices without others noticing, provided they fail the opposed Perception check.

If using Guild Magic, Artificing, Spirit Scripting, or drinking a potion, make a Sleight of Hand check If using Pact Magic or Performance Magic (provided it's singing, or you have a justification to be performing) make a Bluff check

If you beat everyone in the vicinity's opposed check, no one notices that you are using magic...they see the effects, but they don't know you're responsible until they've exhausted most other possibilities.
