Mortal Shell Items and Familiarity Guide

This guide lists every item in Mortal Shell, alongside its Familiarity value and effect. It also talks about the lute because lute is life.

There are almost 75 different items scattered across Mortal Shell, including consumables, upgrades, key items, and equipment. Many of these items also come with a Familiarity score, a 10-dot meter that increases as you use them more and more.

High Familiarity changes an item's effect permanently, and always increases the benefits an item offers in some way. That might be as simple as improving the speed at which a healing item works to reducing its cost. No matter what Familiarity does, you will see increased value for finding and using items when you find them.

This guide lists every item in the game and describes its usage. If the item changes based on Familiarity, that info is listed as well. The categories we won't talk about are Glimpses and Upgrade Key Items. We covered the former in our complete guide to Glimpses.

Key Items like Sacred Glands and Upgrade Items are coming in their own guides, as you'll want to know where to find them and what they do (though we do have a general upgrade guide to get you started).

Also, note that we aren't going into strategies to use any particular item. That's a whole series of other guides. 

Consumable Items

Consumable items are just that: consumable. Once you use one of them, you have one less of that item in your inventory. Use them all, and the item symbol will grey out in the menu and on your shortcut bar.

Some consumables tend to respawn after about every five minutes: mostly things like weltcaps, tarspores, and other plants. Others can be found in the frog chests only unlockable during the Mist.

Tar Items

Technically a type of consumable, Tar items give Tar, Mortal Shell's version of souls. Basically, it's the catch-all currency for upgrading Shells and abilities, as well as for trading. You'll need lots of it for the late game upgrades, too, so get as many of these as you can.

    • No Familiarity bonus.

Unlimited Use Items

As with other examples, Unlimted Use items never expire. Use them as many times as you want without cost or caution. Unless you want to lose Glimpses. Then exercise caution.

  • Disciple's Rag: Switch your weapon to the Smouldering Mace, as long as it's not currently equipped
    • No Familiarity bonus
  • Impervious Lute: Lute is life, and you can play it forever. Never stop playing lute. It is everything.
    • Familiarity 10: You are the best musician. Keep playing lute.
  • Martyr's Shawl: Summon the Martyr's Blade to your hands, so long as you aren't using it.
    • No Familiarity bonus
  • Ornate Mask: Allows travel between instances of Sester Genessa
    • Familiarity 4: Increases Tar gains for one minute
  • Sester's Blessing: Summon the Hammer and Chisel, as long as it isn't currently in your hands
    • No Familiarity bonus

    • Familiarity 2: Lose only half of your Glimpses per use
  • Tattered Vestment: Summon the Hallowed Sword to your hands, so long as you aren't currently using it
    • No Familiarity bonus
