Sculptor's Idols
Initially, a Sculptor's Idol is a place of rest. Commune with the Sculptor's Idol to completely replenish your Vitality and restore one Resurrective Power charge. Communing will also add to your Spirit Emblems as well as any other consumable items in your Quick Items.
After discovering a second Sculptor's Idol, you'll gain the ability to fast travel to other Sculptor's Idol locations you've encountered and activated by communing with them.
As you continue to progress through your mission, you'll begin collecting Prayer Beads. When enough Prayer Beads are collected in your Inventory, they can be consumed to upgrade your maximum Vitality and Posture.
Additionally, once a skill point is earned, talking to the Sculptor will grant the Shinobi Esoteric Text, which allows Wolf to spend these skill points on new skills. There are a number of Esoteric Texts that can be found in the game.

Skills
As you progress and gain experience through gameplay, you'll have the option to apply Skills to your Shinobi through one of three Skill Trees: Shinobi Arts, Ashina Arts, and Prosthetic Arts.
Once acquired, these Latent Skills are always present and don't require activation to use. Skills include reduced visual or audible detection while in stealth, Vitality or Posture recovery, increased healing effects from recovery items, and improved item drop rates from defeated enemies.

Change Form
Change Wolf's appearance from the Change Form Menu.
Regardless of his appearance, Wolf's abilities will be unaffected.
Additional forms will become available by obtaining "Memories of Another".
Reflection of Strength
Reflect upon a previously defeated extraordinary foe to fight them once more within Wolf's memories.
Gauntlet of Strength
By reflecting upon his memories, Wolf can perform a series of one-on-one battles with extraordinary foes he has defeated in the past. Defeat at any point will result in a failed attempt, returning Wolf to reality.
