Keystone

A Keystone is a unique and powerful passive skill node that significantly impacts the way a character is played.

Interactions

Interactions with unique items

Some unique items grant a keystone status without needing to have the keystone allocated in the passive tree. In these cases the status only applies once. If you allocate the keystone and use the unique it will be the same as if you had only done one.

Some unique items have stats which are similar to keystones. These effects are separate from the keystone and will be treated as two different modifiers. Uniques which add a keystone effect will have the exact name of the keystone in their effect list.

Stat removal

• Stat: The stat in question.
• Removed: The stat is removed by this keystone. Keystones that require this stat cease to function.
• Targeted: The stat relies on or is improved by this keystone. If this stat is removed by another keystone, this keystone ceases to give its benefit.

In short, keystones in the Removed column block the benefits of other keystones in the Targeted column for that stat. Only stats for which there is a potential conflict have been listed.

Stat	Removed	Targeted
Evade Chance	Unwavering Stance	Arrow Dancing
Life	Chaos Inoculation	Blood Magic, Pain Attunement, Vaal Pact, Corrupted Soul
Life Regeneration	Vaal Pact	Zealot's Oath
Mana	Blood Magic	Mind Over Matter, Power of Purpose, The Agnostic
Critical Strike Chance	Resolute Technique	Elemental Overload, Perfect Agony, Dance with Death, Second Sight
Critical Strike Multiplier	Elemental Overload	Perfect Agony
Energy Shield	The Agnostic	Eldritch Battery, Eternal Youth, Ghost Reaver, Immortal Ambition, Wicked Ward, Zealot's Oath
Energy Shield Recharge	Immortal Ambition	Wicked Ward
Life Leech Recovery	Strength of Blood	Ghost Reaver

Notes:

• Iron Reflexes is based on evasion, which is not the same as evade chance. Thus it is compatible with Unwavering Stance.
• Vaal Pact + Zealot's Oath: Life regeneration will not apply to energy shields, but energy shield regeneration will still function.
• Vaal Pact + Ghost Reaver: Negates the benefits of each other.
• While Eldritch Battery, Corrupted Soul, The Agnostic, and Divine Flesh can be combined with Chaos Inoculation, it will severely impact the character's surviability.
