The 1.0 ver. of Elden Ring is only available on console discs, and now we have access to the PS4 version. I "ported" all enemy AI, texts and UI to the PC version. Download link for Malenia down below.

Upon encountering Malenia, her AI was tiny bit different, unpolished even in this version of the game. The most noteable change that she still has access to her "old" Waterfowl, which modders have discovered before. This video aims to showcase some of her differences to the patched version:
she's more aggressive in Phase 1
slightly different combos
she blocks many, especially consecutive attacks
old Waterfowl Dance
phase 2 clone attack doesn't do scarlet rot buildup
