Theme and ruleset
Malignant Hearts, Cormond and Varshan defined the first season. Hearts modified jewelry and changed builds through their effects.
Start by the German calendar: 2023-07-20. Version family: 1.1. This season has ended; its original theme is not automatically active in the live game.
How progression worked in this season
Historical sequence for the period’s ruleset. These steps do not reactivate expired seasonal quests or theme powers in the current game.
Start
After campaign completion, begin Burning from Within in Kyovashad and obtain Cormond’s Cage of Binding.
Secure a Heart
Defeat a partly corrupted monster, activate its heart and defeat its fully corrupted return. Match Heart and jewelry socket colors; Wrathful Hearts fit any color.
Reading builds correctly
For a historical build, first identify its heart. An attack plan built around that effect is a different build without it. Compare the underlying skills separately from the seasonal mechanic.
Barbarian: Whirlwind; Druid: Pulverize; Necromancer: Bone Spear; Rogue: Twisting Blades; Sorcerer: Ice Shards. These are historical archetypes for context, not a verified complete tier list.

Match version, class and seasonal mechanic. Record which parts of an old recommendation are still available today.
Choose a goal
Separate leveling, fast farming, boss encounters and high-end challenges. A single tier label does not explain these differences.
