Avoid Big Brain + EscAPADe

Big Brain provides a massive shield scaling with 300% AP, but EscAPADe converts all AP into bonus attack damage. This removes the primary scaling stat for Big Brain, causing the shield to absorb almost no damage. Avoid this pairing because it completely nullifies the defensive value of Big Brain.

Avoid Big Brain + Glass Cannon

Glass Cannon caps your health at 70% maximum and cannot be exceeded by any means. Big Brain's shield is wasted because the health cap defeats the purpose of extra durability. The shield cannot save you from the health threshold restriction, making this a conflicting defensive pairing.

View augment details

Avoid Big Brain + Back to Basics

Back to Basics seals your ultimate ability permanently. While it grants 35% increased healing and shielding, Big Brain's shield is a one-time flat value replenished only on respawn. The shield power bonus is negligible compared to losing your ultimate, and the stat increase does not justify this trade-off.
