Clear answers to the most common DILUC build questions.
DILUC is built as Main DPS · Vaporize / Plunge Carry. Start with Crimson Witch of Flames, use Beacon of the Reed Sea when available, then meet the recommended stat targets before chasing additional damage substats.
Crimson Witch of Flames is the primary recommendation in this guide. The alternative sets above may perform better when another teammate already supplies the same buff or when their substats are substantially stronger.
Beacon of the Reed Sea is the featured best-in-slot option. The weapon section also lists accessible alternatives with their Level 90 stats and the situation where each choice is most useful.
Substats: CRIT Rate / CRIT DMG → ATK% → Elemental Mastery → Energy Recharge.
Prioritize Tempered Sword. Raise the remaining talents according to the priority cards above so resources are spent on the abilities that contribute most to DILUC's role.
Plunge Vaporize is the first recommended composition. The Teams section includes additional premium and accessible alternatives so you can replace unavailable characters without losing the core game plan.
