Crystal

This article pertains to a subject that is not yet released in the Global server of Arknights.

Crystal is an operation mechanic in Arknights, featured in Inudi Harek, Horakhet.

Overview

Crystals are actually treated as an enemy unit that neither does move nor attack, can neither be blocked nor shifted, immune to Elemental Damage and Cold, has an aggression level of -1.

Crystals are initially found in the polluted state which reduces the ASPD of friendly units on the same tile as it by 60 and increases the HP and ATK of enemies by 10%, in addition to giving them additional traits (see Interactions). The Crystal can be purified by attacking it; while it has a mere 20 HP, any damage it took is reduced to 2, and it cannot be defeated even when it has 0 HP; should it takes any further damage at this point, the Crystal will be purified and shatters.

If there are clusters of polluted Crystals, should any of them is purified, others in the adjacent tiles will be purified as well, which can form a chain reaction. Purecrystals can be used to connect separate clusters of Crystals, while Decrystaling Pile can be used to clear out Crystals in its path, whether polluted or purified.
