Derieri Greatsword Build: Fire Support Route
Greatsword is the Fire support route. Current skill data shows team Fire Attack support, Fire Defense reduction, and an Ultimate/Combined Attack damage-taken window, so judge it by the enabled carry and rotation rather than Derieri's isolated hit.
When this answer applies
- ✓Your roster already has a Fire damage dealer worth amplifying.
- ✓The team can align burst during the support windows.
- ✓You are comparing total-team results, not one tooltip multiplier.
What to do next
- 1Start with a Fire carry plus Derieri Greatsword.
- 2Use Guila or Tioreh as owned alternatives when a premium slot is missing.
- 3Compare clear time before and after the support window is aligned.
Evidence boundary
The Fire support role is official. Detailed percentages are reliable secondary in-game data; boss-specific value is unverified.
