Elemental Node

See also: Enhanced Pneumousia Amplifier

Elemental Nodes and Infusion Stones are objects that imbue nearby enemies with elemental buffs. They appear in certain Domains and some parts of the Teyvat overworld. They come in Cryo, Electro, and Pyro variants and provide different buffs depending on the element.

Unlike Elemental Nodes, Infusion Stones are vulnerable to certain attacks and can be destroyed. Once destroyed, applied buffs will immediately be removed. Pyro and Electro Infusion Stones are Geo objects and are weakest to Blunt Attacks. Cryo Infusion Stones are Cryo objects that are weakest to Pyro.

Buffs[]

See also: Elemental Gauge Theory

Nodes pulse once every 15 seconds, buffing all enemies in range:^[1]

Un-buffed enemies gain 3.6 gauge units of the node's element.
- Unlike elemental gauges applied by characters' talents and most other elemental sources, the gauge from the node's buff does not decay over time and instead lasts until depleted by Elemental Reactions.
- The pulse will trigger an Elemental Reaction first if the enemy already has an elemental gauge of a different element.
- Corresponding elements which are not from nodes do not affect the buff, whether before or during buffing.
Buffed enemies gain an additional 1.2 gauge units.
- The max available gauge of this buff is 3.6 units.
Once an enemy's buff gauge is fully depleted, the enemy cannot regain the buff in the next 2 pulses.

Until the Elemental Gauge is depleted, enemies will gain 50% RES to all damage types along with an additional 50% RES to the node's element. They will also gain increased Interruption Resistance with a hyperarmor multiplier of 0.01 and another bonus based on the node's element:^[1]

Cryo: +100% DEF
- This DEF increase is additive with other DEF modifiers (such as DEF reduction talents from characters).
- For example, if the enemy is in the Cryo-enhanced state, and Razor uses his skill to reduce their DEF by 15%, then the DEF of the enemy is multiplied by $2 - 0.15 = 1.85$ .

Pyro: +40% ATK
- This ATK increase is additive with other ATK modifiers.
- For example, after the enemy gets the Pyro-enhanced state, Diona uses her 4th Ascension Passive to reduce their ATK by 10%, and the ATK of the enemy is multiplied by $1 + 0.4 - 0.10 = 1.3$ .

Electro: +50% Cooldown Reduction
- This effect can be observed on some enemies such as Electro Cicin Mages, increasing the rate at which they are able to use their Supercharged Shield attack, but it is not yet known exactly which other enemies and attacks it affects.
