July 2025 — D2R-Reimagined mod: Completed a data-driven itemization and crafting balance pass, bug fix, and targeted balance tweaks that strengthen progression and gameplay predictability across endgame content. Key deliverables include a global itemization and crafting tuning pass (covering Tal Rasha’s Wrappings, item rarities for rings/amulets/charms, crafting charms, unique jewels/facets), with refinements to data-driven item behavior and loot considerations (including Treasure Hunter and Shako). Implemented a Concentrate interaction bug fix to prevent carnage usage while shifted, and performed poison skill balancing for Necromancer and Druid along with monster behavior adjustments (notably increased cow speed) to improve combat balance and pacing. The release emphasizes business value through clearer power progression, richer crafting paths, and more predictable combat dynamics, underpinning player retention and longer-term engagement.
