Stuck on final boss phase 2 with magic build; seeking gear, loadout and timing tips

[Zoey65]

I'm stuck on the final boss in a popular action RPG, and despite watching several boss fight strategy guides, I can't seem to get past the second phase. My character is a magic-focused build, and the boss has rapid, close-range attacks that interrupt my casting. For players who have beaten this fight with a similar build, what specific gear or spell loadout did you find most effective? How did you manage your stamina and positioning to create casting windows, and are there any tells or audio cues for its big attacks that the guides often miss? I'm also wondering if I should respec some points into survivability or if I just need to perfect my dodge timing.
