<!-- {{#ev:twitchvod|v97697764|300px|right|An overview of keystones|frame}} assuming this function is trying to locate a twitch vod that is no longer available -->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.

'''Examples:'''
* {{il|Malachai's Simula}} adds the keystone effect.
* {{il|Prism Guardian}} adds the keystone effect for specific skills.
* {{il|Chin Sol}} does not add a keystone effect.

===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.

{| class = "wikitable"
! 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.
