[StarRail2.7] Firefly In-Depth Build Guide🔥

Should you pull for Firefly?

➥ Firefly is a Fire character following the path of the Destruction. She excels at dealing Break DMG to enemies, and can apply Fire Weakness to enemies regardless of their Weakness Type during her Ultimate. Additionally, she can also heal herself when using her Enhanced Basic Attack and/or Enhanced Skill. If you are looking for a Fire DPS or want to play Break teams, Firefly is a great option to pull for!
➥ However, if you like Firefly, go for her! Remember, enjoying the game is more important^^

FAQ & NotesE1 or S1? Firefly's E1 ignores a certain percentage of the enemy's DEF and Skill Points (SP) will not be consumed when using Enhanced Skill - a great Eidolon if the team is very reliant on SP. Plus, her E2 is a good stopping point, so if you do get her E2 while pulling for E1, it's a bonus! However if you like her signature Light Cone, go for it! Enjoying the game is more important~
Try to hit at least 360% Break Effect on Firefly during combat so that she can deal more Break and Super Break DMG!
