In Diablo 4 Season 1, the most likely way to find Caged Hearts is by killing a Malignant adversary in the wild and performing a ritual on its heart to kill more Malignant monsters! You get a Caged Heart after killing them all.
Seasonal things let you enhance your gear to epic levels, making endgame easier and strengthening your character.
Some Caged Hearts give any character a strength boost, while others help certain character builds. Diablo 4 Season 1 Caged Hearts vary in quality.

Diablo 4 adds strongholds. Monsters, bosses, and great riches abound in these hard game zones.
The game has over 10 Strongholds across the map. After fighting all the evil monsters and bosses in these places, your class will level up with the loot.
Ruins of Qara-Yisu: Find and destroy three Infernal Spires to wake up shaman Utulku and clear this Southeastern Stronghold. To finish, defeat this boss.
Temple of Rot: This Stronghold in the southwest of Dry Steppes requires extra labor to clear. Kill all monsters in The Garden, Courtyard, and Temple. To clean up, destroy the monster in its lair.
