Thief's Mark is a Yellow tool that you can equip to your crest in Hollow Knight: Silksong. Check out how to get Thief's Mark, its location, and its effects here!
List of Contents

First, head to the Blasted Steps and make your way to the top-left corner of the area. You’ll find Grindle and his shop here. Speak to him to purchase the Thief’s Mark.

Grindle will sell you the Thief’s Mark for 350 Rosaries. This is the only way to get the Thief’s Mark, so make sure you have enough rosaries to purchase it.

The Thief’s Mark lets you gather 60% more Rosaries from enemy drops, but with the downside of losing 15–20% of your current Rosary count whenever you take damage.
It’s a great tool for farming Rosaries, especially when paired with the Magnetite Dice, but be sure to farm in areas where you can safely take on enemies without getting hit.
