Arknights: Endfield announces Sketches of Lost Heirlooms
Arknights: Endfield has announced the "Sketches of Lost Heirlooms" version update, introducing the new [Backup Power] feature that automatically supplies unlimited electricity when a region runs out of power. The update also adds a [Regional Overview] feature to the [Regional Development] screen and a [Multi-Clog Auto-Fix] feature for the [Expanded Crucible]. Additionally, the update includes optimizations for Wuling power connections, grid display effects, and mission priorities.

AIC Factory & Regional Development Improvements


- New [Backup Power] Feature: If a region runs out of power when you're playing, its backup power will automatically activate to temporarily supply unlimited electricity to all facilities, maximizing AIC uptime. The backup power will drain after running for a period of time, after which it requires a cooldown period to recharge. You can use [Backup Power] as a buffer while adjusting your power layout and overhaul the power grid before it runs out. Alternatively, you can choose to disable the auto-activation and turn it on manually when power is depleted.
- New [Regional Overview] Feature: A new [Regional Overview] feature has been added to the [Regional Development] screen, providing an overview of current information in the Regional Development System, including [Stock Redistribution] and [Depot Node], while allowing you to quickly view their locations on the map. For instance, you can directly check the current level and upgrade costs of a [Stock Redistribution Terminal], then jump straight to the map and view its location. Similarly, when purchasables are about to reach the limit, you can click the corresponding reminder to jump straight to the [Stock Redistribution] screen and make a trade.
- New Expanded Crucible Feature [Multi-Clog Auto-Fix]: When the [Expanded Crucible] is running multiple production formulas, if all of these formulas are clogged, the [Expanded Crucible] will automatically remove all items from the cache to ensure that reactions proceed normally. This option is enabled by default, and its status will be saved along with the blueprint.
- Wuling Power Connection Optimization: The [Xiranite Pylons] and [Xiranite Relays] within the Core AIC Area can be connected to outer Xiranite facilities.
- Grid Display Effect Optimization: Optimized the grid display effect when placing facilities in transition zones between steep slopes / cliffs and flat ground.

Interactions and Quality-of-Life Improvements



- New Gear Artificing [Auto-Fill] Feature: When artificing gear, you can bulk-select multiple pieces of unartificed gear as the artificing materials according to a default sequence, then have artificing continue until it succeeds, reducing repetitive actions. If the artificing succeeds early, any unused gear and Gear Artificing Catalysts will be automatically returned.
- New [Weapon Batch Dismantling and Lock Management Features]:
- Weapon Essence Acquisition Optimization: Added a new [Essence Wishlist] feature, which unlocks at Exploration Level 4. You can open the wishlist in the Severe Energy Alluvium challenge screen or [Valuables Stash - Essences] and select multiple weapons. When an acquired [Flawless Essence] matches all stats of any weapon selected in the wishlist, the essence will be automatically locked and marked as a [Perfect Match].
- Off-Screen Enemy Attack Warning Optimization: Added visual warning effects for attacks from off-screen enemies, making it easier to identify threats and dodge when fighting large groups of enemies.
- Combat Lock-On Optimization: Optimized the indicator when switching locked targets, making the currently locked target easier to distinguish.
- New Return Option After Visiting Friends: Added a [Return to Dijiang] option after ending a friend visit, which allows you to return to your own Dijiang.

Optimization Content Still in Development
- Camera System Optimization: Added custom operator photo poses and positioning. When taking photos, you can now freely move the operators currently on the field and designate their poses.
- Story Dialogue Experience Optimization: Added definitions for key terms to help you more quickly understand the worldbuilding and lore.
- Top View Mode Experience Optimization: When selecting from multiple overlapping targets in top view mode, a menu will pop up for you to confirm your selection, making production line management more precise and convenient.
- Multi-Mode Facility Placement Optimization: When placing AIC facilities that can toggle between multiple modes, you can now select the desired mode before placing the facility.
- Shared Facility Repair Optimization: Shared zipline facilities will now be automatically repaired while you use them.
