| —Description of operations featuring the Gramophone |
The Gramophone, officially the L-44 "Gramophone", is a static device in Arknights. Despite the name which refers to a sound recording instrument, Gramophones behave more like autonomous guard towers utilizing offensive and healing Arts as a deterrent to wild creatures and hostile invasions.
Initially Gramophones are "neutral" and have no use for both the player and enemies, usually starting with 50 SP. The player can deploy units on a Gramophone's "Protocol Entries", which are tiles marked by a lightning symbol on it, to have the Gramophone restore 1 SP every second; a Gramophone's Protocol Entries are located in the adjacent tiles to it with some overlapping with each other, and more units will speed up the SP restoration. Once the Gramophone's SP is maxed out at 100, it will become friendly.
Certain enemies, notably Leithanian Whisperers, can "contest" Gramophones by causing one to lose 1 SP every second with their "leash" ability. Should a Gramophone's SP is depleted, it will become hostile. Some enemies, notably Winterwisp Blood Shamans and Mudrock, can completely deplete a Gramophone's SP, essentially turning it hostile instantly.
Gramophones' attacks target the enemy with the highest maximum HP over the others, which can be very useful against Mudrock Zealots to counter their Arts-absorbing barrier and Mudrock Colossi to make their high HP not much of an issue.
A neat way to capture Gramophones early-game is to bring Summoner Supporters or Trapmaster Specialists and deploy their summons/traps on the Protocol Entries. This will allow the player to capture the Gramophones very early into the operation, and to recapture/secure it without consuming deployment slots or being targeted by enemies and hostile Gramophones (in the case of traps) for a smaller and predictable DP cost.
