Honestly, I didn't think about that. The way it's worded right now, it would work that way.
It's a cool idea. A dip in binder with Improved Binding wouldn't be a bad idea for crafting-focused characters. I think I'll leave it for the cool factor, unless there's an objection with justification.
Thanks. It's my first vestige. Good to see all the positive feedback.Also, awesome vestige. Definitely going to use this in my campaign.
