    Phase 2: Vile Effigy & Hoarfrost

    Baal creates an identical clone and casts wide cold pushback waves.

    • Hoarfrost: Massive V-shaped wave causing knockback and chill; counter with Unstoppable.

Site update log

  • S15 affix demand refreshed: 4,053 samples with per-class affix priorities recalculated; tuning prism pools and the loot filter dictionary were re-signed in the same batch.
  • S15 wrap-up data refresh: 15 new builds and 20 new Tower runs. The 20 runes removed this season stay in the codex and search, marked "Unavailable this season", and the dual-rune meta now counts only combinations that are still socketable this season.
  • New Tuning Prism affix pool page: see exactly which affixes each of the six Horadric Cube tuning prisms can roll — search affixes, filter by prism, or reverse-look-up which prism rolls a given affix. Tempering rows in the affix table now label their prisms too.
