Echoes of the Philosophers.

When you make an ability check, you can call on one of the souls within the Stone to guide you, which gives you Advantage on the check. Once you use this benefit, you can't use it again until you finish a Long Rest.

When you use this benefit, a trace of that philosopher lingers in you for 1 hour. The DM describes a quirk of theirs that you roleplay: a habit, an accent, a strong opinion, or a memory that isn't yours.
