An overview of keystones

Keystones are unique and powerful passive skill nodes that significantly impact the way a character is played.

Interactions

Stat removal

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

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

Stat	Removed	Targeted
Armour	Acrobatics	Iron Reflexes
Energy Shield	Acrobatics	Ghost Reaver, Zealot's Oath
Evade Chance	Unwavering Stance	Arrow Dancing
Life	Chaos Inoculation	Blood Magic, Pain Attunement, Vaal Pact
Life Leech	Vaal Pact	Ghost Reaver
Life Regeneration	Vaal Pact	Zealot's Oath
Mana	Blood Magic
Critical Strike Multiplier	Elemental Overload

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.

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.
