Sandstorm
The Sandstorm is an operation mechanic⁎ in Arknights, introduced in Operation Originium Dust.
Overview[edit]
| “ | Allied units caught inside the sandstorm will have reduced ATK, continuously take damage over time, and have extended redeployment time; Enemy units will instead be slowed. | ” |
| —Description of operations featuring the Sandstorm |
The Sandstorm blows toward a certain side of the operation's map, causing friendly units who are exposed to it to have their ATK reduced by 50% and lose HP over time (actually taking True damage) at a rate of 100 every second; should a friendly unit exposed to a Sandstorm leaves the map, their redeployment time will be increased by 50%. Enemies exposed to a Sandstorm, on the other hand, will have their MSPD reduced by 40%, but some benefits from it (see Interactions).
Sandstorms last for a long period of time which counts from the start of the operation and can even change its direction in certain operations[note 1], thus it is important to adjust the deployment positions carefully to mitigate its effects. Fortunately, Sandstorms can be blocked by Dirt Mounds, but the strong gust continuously drain the Mounds' HP unless if they are reinforced via Reinforcement Devices.
Interactions[edit]
| Enemy | Interaction |
