Guinaifen
Who is Guinaifen?
Guinaifen is a 4★ Fire DoT support following the Nihility Path. She applies Firekiss (a stackable Burn amplifier) via her Skill and provides teamwide DoT vulnerability via her Talent. In DoT teams she acts as a strong budget support pairing with Kafka and Black Swan, increasing the damage of all DoT effects on the field. Source: prydwen.gg.

Frequently Asked Questions
Does Guinaifen replace Sampo in DoT teams?
They fill similar but not identical roles. Guinaifen is better in Fire-weak content and provides stronger per-hit DoT amp; Sampo provides a teamwide DoT vulnerability debuff from his Ultimate. Both can be run together.
What Effect Hit Rate does Guinaifen need?
67% to guarantee Firekiss application on her Skill. After that threshold, focus on ATK% and SPD.
