Summon
In Arknights, summons are units that are deployed by certain Operators to help them offensively or defensively.

Trap
Traps are deployed automatically by certain Operators and manually deployed by Trapmaster Specialists, in which case they must deployed on tiles without enemies, although Levitating the enemies gives the player a moment to deploy traps beneath them. When a ground enemy (and only ground enemies) is too close to a trap, it will be triggered; note that invisible enemies will not trigger traps.
Trapmasters can notably replenish their trap's count with their skills.
All traps are invulnerable and do not use up the Unit Limit.
Trap | Operator | Use |
---|---|---|
Deals Physical damage and Slows the victim when triggered, with the former dealt twice if the Bomb has been deployed for at least 3 seconds. Cannot be deployed at will, instead deployed through "Courtesy Gift". | ||

Reinforcement
Reinforcements are utilized by Tactician Vanguards and can only be deployed on a tile within their attack range, which is designated as a "Tactical Point". When the Tactician attack enemies being blocked by their Reinforcement, the damage they deal is increased.
Should a Reinforcement be KO'd or retreated, it will revive itself over a period of time during which it is invulnerable but can neither attack nor block enemies. Therefore, the Reinforcement can only be relocated by redeploying their respective Tactician.
All Reinforcements cost no DP to deploy and do not use up the Unit Limit.
Reinforcement | Operator | Use |
---|---|---|
Can copy an Operator by placing them on top of the Flowing Shape while its skill is active, giving the Shape most of the Operator's attributes and a trait to either Steal enemy ATK/DEF or create more of itself periodically depending on whether the copied Operator is a melee or ranged one. | ||
Nothing special
| ||
Can attack Sleeping enemies, which it will target over the others. | ||

Support Device
Support Devices are utilized by Artificer Supporters to augment friendly units. An Artificer can only have a limited number of Support Devices deployed at a time.
All Support Devices do not use up the Unit Limit, are invulnerable, and will self-destruct after some time have passed from when they are deployed (except Stainless' Support Devices).
