Use this 8th Sword guide to compare base and evolved forms, identify the relevant build questions, and confirm live requirements before spending resources.
Guide overview
Farm the current raid panel, not an old percentage
The earlier guide describes a Spirit City Raid Act 3 route and a Hard-mode equipment context. That gives a player a clear place to investigate, but it does not guarantee the same completion requirement or chance in the live game.
Before committing a farm session, open the raid selector and record the currently listed difficulty, rewards, and pity or progress information. That avoids building an evolution plan around an event-era or patch-era value.
Separate base and Berserk questions
Keep 8th Sword separate from 8th Sword (Berserk). Treat the evolution screen as the authority for the materials and unlock conditions, then inspect which passives are present at your current form.
Hair Bells appears as the matching equipment in earlier gear lists. Read its live effect and the unit's placement behavior before rerolling, because gear value depends on how many copies you can field and which encounters you are clearing.
