How it works
Build Charge through Gustave’s actions, then spend a full gauge with Overcharge at a meaningful moment. His kit rewards patient setup instead of pressing the strongest button as soon as it appears.
Practical strategy
Use Gustave to learn timing and Break windows. Aim to release Overcharge when the target is vulnerable and your other party members can follow through.
Mistakes to avoid
Using Overcharge before a meaningful damage or Break opportunity wastes its value.
