Why Natsu Matters
Natsu matters when it speeds up your clears, makes boss farming safer, or takes pressure off the rest of your build.
Moveset
Natsu uses the following named moves:
- Z - Dragon Fire Pillar
- X - Dragon Fire Surge
When to Keep Natsu
Keep Natsu when it is clearly solving a current account problem better than your existing Soul. That can mean better clear speed, cleaner boss uptime, safer farming, or simply enough quality that you can stop burning resources on desperate rerolls.
When to Replace Natsu
Replace Natsu when your account is finally stable enough that a stronger Soul would create a real upgrade instead of only a more expensive grind. A Soul is not weak just because something rarer exists. It becomes replaceable when your route has outgrown what it solves.
How to Judge This Soul
Compare this Soul with what you are using now. If it gives you cleaner farming, faster bosses, or enough power to stop rerolling for a while, it is doing its job.
