Klee’s Elemental Skill throws a bomb that deals AoE Pyro DMG and eventually splits into mines that explode on contact or after a short delay. Her Elemental Burst continuously summons Sparks ‘n’ Splash to attack nearby enemies.
Klee’s Normal Attacks, Elemental Skill, and Elemental Burst can grant her Explosive Sparks, allowing her Charged Attack to transform into a stamina-free Boom-Boom Strike.
With at least 2 Hexerei characters in the party, during her Burst, Klee’s third Normal Attack can consume an Explosive Spark to release a Boom-Boom Strike. Additionally, each time Klee deals damage with different attack types, she gains Boom Badges, which further strengthen her Boom-Boom Strike based on the number of badges she holds.
