| —Trait description |
Dollkeeper Specialist is a branch of the Specialist class in Arknights.
Dollkeeper Specialists are melee Operators with above-average stats that makes them a solid combat unit. Notably, they have the ability to switch into a "Substitute" for 20 seconds upon taking fatal damage, after which they return with full HP and 0 SP; the time remaining before the Substitute is switched back to the Dollkeeper is shown in place of the Substitute's SP meter. In both cases, all buffs and debuffs except Elemental Damage applied on the Dollkeeper and their Substitute are cleared, and the most recently switched one will be treated as the last deployed friendly unit.
The Substitute has identical stats to the Dollkeeper Specialist themselves, but cannot block enemies and the Dollkeeper will be considered to have been knocked out when the Substitute is defeated, forcing them to be redeployed. It is worth noting that the Dollkeeper and their Substitute are invulnerable while switching between each other.

Strategies
- Thanks to the Dollkeeper Specialists' Substitute-swapping mechanic as described above, they can be used (with or without help from Medics) as fairly strong decoys against ranged enemies capable of constantly inflicting debuffs (e.g Acid Originium Slug, Armorless Union Cleanup Squad, Armorless Union Third Squad).
- Most Dollkeeper Specialists' skills tend to make them switch to their Substitute by lowering their HP under certain conditions.
Modules
- The PUM-X Module improves the Substitute's damage output, especially if the Dollkeeper Specialist already have high ATK to begin with.
- The PUM-Y Module allows the Substitute to last longer on the field, especially if the Dollkeeper Specialist already have high HP to begin with.
