NOTE ABOUT TRIDON'S SHIELD

Tridon's shield from his BB and SBB are currently bugged. When an enemy destroys the shield, the unit will still retain the shield's DEF and element until the enemy's attack is finished.

In other words, do not use Tridon's shield to take Gravion's "Heavy Gravion" attack. Since the shield has lower DEF than your units (your units should have over 1000 DEF), you would be taking more damage with the shield than without the shield.

Use Tridon's shield with caution.
