Crystallize

Crystallize

First Element	Geo
Second Element	Any 1 of the following:
Effect
Creates a Pyro, Electro, Hydro, or Cryo crystal that will provide a corresponding Elemental Shield when picked up.

Crystallize is an Elemental Reaction in Genshin Impact. Elemental Reactions are a combat mechanic in Genshin Impact. When a Playable Character inflicts an Enemy with an Element, the Enemy gains a decaying aura of that Element, which can be combined with a new compatible Elemental Aura to lead to an Elemental Reaction. This mechanic can also be used on players and objects.

Elemental Reactions can be triggered using the 7 Elements in Genshin Impact, Anemo (Wind), Geo (Earth), Electro (Lightning), Dendro (Nature), Hydro (Water), Pyro (Fire) and Cryo (Frost).

Crystallize Reaction Genshin Impact

Crystallize will create an Pyro, Electro, Hydro, or Cryo elemental shard depending on the Element used with Geo in the reaction. When a Playable Character walks over the generated shard, they will gain a Pyro, Electro, Hydro, or Cryo elemental shield depending on the elemental shard picked up.

The shards last on the field for roughly 18 seconds, and the shield lasts for about 15. Shields do not stack, and will simply replace the existing shield and renew the duration. Elemental Shields are block much more damage against attacks of the corresponding element.

Crystallize's shield health will scale with Character level and Elemental Mastery, with the base damage of the reaction being multiplied by these variables. ATK, Crit rate, Crit DMG and any other stats besides CL and EM will not impact the damage of this reaction.

How to trigger Crystallize Genshin Impact

Crystallize can be activated by combining the Geo aura with the Pyro, Hydro, Electro or Cryo aura or vice versa. This can be achieved by either applying both auras with the Playable Characters in your party, or by applying Pyro, Hydro, Electro or Cryo/Geo to an Enemy who already has the complementary aura, such as a Geo Slime or a Pyro, Hydro, Electro or Cryo Slime.

An example of this reaction is shown below with Ice Slimes and Zhongli. In the image, Zhongli uses his Elemental Skill Dominus Lapidis to deal AoE Geo damage to the slimes on the field. This reaction creates Cryo Elemental Shards, which were picked up to give Zhongli a blue shield, which is most effective against Cryo attacks.
