Mortal Shell 2: All Tarstones And What They Do
Tarstones can drastically change the way you play Mortal Shell 2.
Tarstones can drastically change the way you play Mortal Shell 2.

Tarstones are equippable items that can dramatically change how you play Mortal Shell 2, from elemental weapon infusions to entirely new combat abilities. There are a lot of them, and knowing what each one does before you equip it saves a great deal of guesswork.

Combat in Mortal Shell 2, the latest action RPG from Cold Symmetry,  revolves around five interconnected systems: the Shells you inhabit, the Weapons and Sidearms you wield, the Seals that shape your defensive options, and the Tarstones that let you customise all of the above.

Your loadout has four Support Slots, which hold passive Tarstones offering straightforward buffs to things like critical chance, damage, or survivability. On top of that, both your weapon and your sidearm each carry three additional slots of their own, split between one Ability Tarstone, one Combat Tarstone, and one Infusion Tarstone per weapon/sidearm. 

Ability Tarstones grant you powerful active abilities fuelled by resolve, Combat Tarstones alter your melee combos and projectile behaviour in combat, and Infusion Tarstones imbue your weapon or sidearm with elemental and status effects. Not every Tarstone is compatible with every weapon or sidearm, so keep an eye on what actually fits your build.

With so many available, it helps to know what you're working with. Below is a full breakdown of every Tarstone in the game, organised by category.

Support Tarstones

Support Stones are passive buffs that improve your general combat effectiveness without changing how your attacks fundamentally work. They are a reliable foundation for any build.

Before committing to high-cost Ability Stones like Hand of Rock or Summoning Stone, make sure your build includes enough resolve generation through Support Stones like Devout Stone or Zealot's Stone to use them reliably in combat.
