Investigation Zone

Investigation Zones are special exploration areas in Zenless Zone Zero that change the interface to Investigation Zone Mode. These areas give the player access to most system functions available in normal city areas, as well as allowing the use of Agent Combat Skills. Investigation Zones can be navigated through Fissure Beacons, which act as teleport points and restore the HP of Agents in close proximity.

Investigation Zones can be found in (Hollow) Aerospace City, (Restricted Area) Booastrum, and Scamall Hollow.

Suibian Temple Items

Lumite Ore, Inert Ether Canister, and High-Entropy Alloy can be collected in Aerospace City Investigation Zones and respawn daily. Only 700 of each item can be obtained per day. These items are used for Good Goods exchanges and Yum Cha Sin order submissions.

Enemies

Various common and elite enemies are found throughout Investigation Zones, which respawn every 30 minutes and upon reloading the area. A maximum of 2400 Trainee Investigator Logs (240,000 Agent EXP) and 800 W-Engine Batteries (80,000 W-Engine EXP) can be obtained from enemy drops each week. This roughly translates to ~425 battery of Agent EXP and ~105 battery of W-Engine EXP total and around ~6-7k Denny per run (~60-70 battery of Denny when capped on EXP materials). This nets a total of (425 + 105 + 65) = 595 battery per week.

Type	Denny	Agent EXP Material	W-Engine EXP Material	Note
Elite	100-200	3-4	2-3	Only 24 across the entire zone
Common	20-30	0-2	-	~160 across the entire zone
