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

- Vaal Pact + Ghost Reaver: Negates the benefits of Vaal Pact.
