Casters are essential for dealing Arts damage, which bypasses physical defense and is crucial against heavily armored enemies. Their archetypes include:
- Single-Target Casters (e.g., Amiya, Haze, Eyjafjalla, Ceobe): High single-target Arts damage. Amiya is your starter Caster and remains viable.
- AoE Casters (e.g., Lava, Gitano, Ifrit, Dusk): Deal Arts splash damage to multiple enemies. Excellent for clearing waves of high-DEF enemies.
- Mech-A-Casters (e.g., Click, Passenger, Goldenglow): Summon drones or have unique targeting mechanics, often with high burst or sustained damage.
- Splash Casters (e.g., Mostima, Leizi): Unique AoE patterns or crowd control.
Invest in at least one Single-Target Caster (Amiya is good) and one AoE Caster (Lava is a solid 3-star). For builds, prioritize ATK and leveling skills that boost Arts damage or provide utility. Modules often enhance their damage output or range.
