CRIT Rate / CRIT DMG

Klee has access to a number of animation cancels that allow her to deal damage with her talents faster than normal. Her A1 grants her "Explosive Spark" stacks when she does a Normal Attack, Skill or Burst that when consumed, give her Charged Attacks extra DMG% and not consume Stamina.
Hexerei effects give her up to 150% DMG to her Enhanced Charged Attacks - this effect should always be active at max stacks.
Her optimal combos include:

N1C/N3 in teams where hexerei resonance is active
N1C/N1W in teams where it isn't

Klee requires great positioning, or the use of a shielder, as she is extremely squishy and prone to interruptions. This is partially mitigated in her best teams, which focus on Overload with Chevreuse, and also provide amazing stagger that helps her immensely with not getting hit. Even with this consideration, her best teams normally don't include a shielder, she can often get knocked around and even KO'd in the midst of your rotations. Running a shielder makes survivability with Klee more comfortable, but at the cost of total DPS. You can choose teammates depending on your level of skill and comfortability.
Regarding Weapon Choices: Weapon rankings assume Hexerei Resonance is active. The following are weapon rankings:

The Widsith: At R5, this weapon performs closer to Tulaytullah's Remembrance. Klee cannot reliably utilize the Elemental Mastery buff, should she acquire it.
Solar Pearl: At R5, this weapon performs slightly worse than The Widsith R5.
Flowing Purity: Calculations assume you clear the BoL.
Lost Prayer to the Sacred Winds: Assumed 12 DMG% averaged.
Kagura's Verity: Assumed 2 stacks on passive.
Tulaytullah's Remembrance: Averaged 25 Normal Attack DMG%.
Surf's Up: Dynamic stacking.
Flowing Purity R5: This weapon is calculated with the assumption that the BoL is instantly cleared. If this weapon is paired with Fragment of Harmonic Whimsy (4) at max stacks, this weapon can perform as well as Tulaytullah's Remembrance.

Regarding Artifact Sets:

Lavawalker (4): Klee's kit makes it harder to utilize Vaporize and Melt the same way another Pyro carry would, but her constant Pyro application makes Lavawalker (4) a viable set.
Desert Pavillion Chronicle: Klee naturally uses her Charged Attack early on in the rotation making Desert Pavillion Chronicle (4) a viable set.
Echoes of an Offering (4): With a 50.2% proc chance on average that gives Flat DMG to her Normal Attack, this set is competitive to Lavawalker (4) and is easier to farm.
Fragment of Harmonic Whimsy (4): This becomes Klee's best set when you are specifically using Flowing Purity. For this reason, this set is not a set you should farm for and is only recommended if you already have the set on standby.
