CRIT Rate or CRIT DMG

1) Elemental Burst: Fiery Rain

Offensive stats do not need to be considered outside of Energy Recharge. CRIT Rate is helpful if using Favonius Warbow.

1) Normal Attack: Sharpshooter
2) Elemental Skill: Explosive Puppet
3) Elemental Burst: Fiery Rain

With the exclusion of those playing a hybrid build focusing on Physical and Pyro damage or with her C6 (Increases Attack), Energy Recharge and Elemental Mastery can be ignored as well as her burst and skill.

Amos' Bow

Thundering Pulse, Sharpshooter's Oath, Prototype Crescent, Hamayumi, Blackcliff Warbow, Hunter's Path

Elemental Mastery

1) Normal Attack: Sharpshooter
2) Elemental Skill: Explosive Puppet
3) Elemental Burst: Fiery Rain

The most important part of this playstyle is to make up for the low scalings on her charged shot by building up high CRIT DMG and consistently landing headshots (weak-point hits) for guaranteed CRIT hit.

*If playing against enemies with no weak-points or World Bosses, CRIT Rate weapons can be better for balancing your CRIT ratio.*

Elemental Mastery sands is conditionally better, but she must be in a Melt or Vaporize team.

The Stringless

Windblume Ode, Raven Bow, Elegy for the End

<sands> Elemental Mastery
<goblet> Elemental Mastery
<circlet> Elemental Mastery

Elemental Mastery

Talents do not have to be leveled for this build, as her raw Pyro damage is negligible.

It's not recommended to farm Crimson Witch of Flames for just Burgeon Amber.
2-piece mixes of any Elemental Mastery +80 sets work too.
