The Tribolt is a steel rod, with a ring-like head and two small spikes. Its primary feature is a trio of large yellow crystals attached to the head with metal plates.
Initially, it slightly boosts Natalie's Magic Attack, HP, Defence, and Magic Defence, as well as giving her a slight resistance to Thunder and Wind - on the other hand, her Evade and Earth resistance suffer substantial penalties. As the Tribolt levels up, the Magic Attack and elemental resistances increase rapidly, maxing out at 50% each. At Level 4, the HP, Defence, and Magic Defence boosts increase slightly as well.
In combat, the Tribolt boosts the power of Natalie's Thunder-based skills, as well as giving her variable-element skills 50% Thunder damage, a chance to inflict Stun, and a chance to cast Thunderbolt automatically.
