Crystallize
Last updated 2025-09-09
Crystallize is the Elemental Reaction triggered by inflicting Geo on a target that is already affected by Electro/Pyro/Hydro/Cryo.
Crystallize deals no DMG. Instead, this reaction generates a matching Electro, Pyro, Hydro, or Cryo Elemental Shard that can be picked up to gain an elemental shield of the corresponding element.
Overview
Crystallize shards last on the field for 15 seconds, though there is a short delay before they can be picked up. If more than 3 shards are on the field, after about 2 seconds all shards except the 3 newest ones will disappear. The shields they grant last for 15 seconds. Only a single Crystallize shield can be active at any time; picking up another shard overwrites the old Crystallize shield. Crystallize shards cannot be picked up by enemies.
Crystallize can only be triggered once per second on the same target.
Note that Geovishap Hatchlings and the Pure Geo Hypostasis can create Geo Elemental Shards during combat, but these are different from the Elemental Shards generated by Crystallize. While the shards and the shield granted when picked up look similar aside from the color, the resulting Geo shield can coexist with regular Crystallize shields—it does not override them.
Shield Health
Character Level vs. Crystallize Shield Base HP
A Crystallize shield's base health (damage absorption) is derived from the triggering Geo user's level, and is then increased by a certain percent depending on the Geo user's Elemental Mastery attribute.
Like all other shields, these elemental shields absorb a set amount of damage before breaking and are 250% effective against their own element (meaning they only take 40% as much damage from said element compared to others[1]) and increase Interruption Resistance while active.
Crystallize shields can coexist with other shields, but each shield will take full damage at the same time (before accounting absorption efficiency).[2]
A character's Shield Strength attribute reduces the damage taken by any shields they have while they are active, rather than increasing the HP of shields they create.[3][4]

Shield HP vs. EM (with a level 90 character triggering the reaction)
