[Deep Containment Zone Info]
- The Deep Containment Zone is a weekly boss challenge where you form a team of four hunters and a Legacy (Successor or Remnant Power) slot.
- You can check the featured experiment boss's element, passives, and special rules that apply each week, such as Anomaly Reports.
- A difficulty is recommended based on your Total Power, but you can also adjust it manually.
- The dungeon's element and Anomaly Report effects change with each weekly reset.
- Multiplay is available, allowing you to consume additional Deep Containment Zone Keys to increase the number of rewards earned in a single playthrough.
- Deep Containment Zone Keys are deducted each time you clear a dungeon, and the menu will show you how many you have remaining.
- Deep Containment Zone Keys are replenished for free every week and additional keys can be purchased at the shop.
*If you purchase additional keys from the shop or obtain extra keys through events while already having the max number of keys, you can hold more than the max limit.
*Free keys only go up to the max limit, and keys aren't replenished if you've already exceeded the limit.
