Understand the Brain Overload (BOL) system in 13 Sentinels: Aegis Rim. Learn why you should never use Recover to preserve your Win Streak for Mystery Points.
Walkthrough
- 1Being on attack adds 500 BOL to a unit.
- 2Being on defense does not add BOL, but also does not reduce it.
- 3The only way to reduce BOL (without using the Recover option) is to have a unit reach or exceed 1000 BOL, causing them to become Overloaded and sit out a battle.
- 4You should avoid using the Recover option because it resets your Win Streak.
- 5Maintaining your Win Streak raises your score, which grants extra Mystery Points.
- 6These Mystery Points enable you to unlock all Mystery Files without needing to grind repeat missions.
- 7The Brain Overload system pushes you to use everyone instead of just one team.
- 8It is impossible to mismanage BOL so badly that you must use Recover, as a maximum of 6 units can be overloaded at once, always leaving 7 units available.
- 9You can replay an earlier wave (e.g., Area 1, Wave 1 on Casual difficulty) to reduce BOL on a specific unit without significantly impacting your progress or Win Streak. This is useful if an overloaded unit is needed for a bonus objective.
- 10Therefore, you should never use the Recover option, even on Casual difficulty, to ensure you have enough points to unlock all Mystery Files.
Tips
- For a personal challenge, you can attempt a one-run playthrough, completing every wave in order without replaying. A suggested team for each wave that manages BOL is available for this challenge.
- Replaying an earlier wave, even with just one Sentinel on Casual difficulty, can clear the overload off any unit and accumulate BOL on only one unit.
