Transmitter Antenna

A quest head armor piece that disrupts spellcasting across the entire battlefield. Reduces the wearer's spell costs by 2 mana and scrambles every spell cast by any cat for the rest of the battle, randomizing outcomes in chaotic fashion. Grants the Metal status. Part of the Bionic and Cyborg sets. Obtained by defeating the C-1000 boss.

The mana cost reduction makes spellcasting cheaper for the wearer, but the spell scrambling affects all casters equally — allies and enemies alike have their spells randomized. This creates a chaotic battlefield where predictable spell interactions become unreliable. The Metal tag enables interactions with magnet-based passives and other metal-synergy mechanics. Because spells are scrambled for everyone, enemies who rely on scripted spells become more erratic and less dangerous.

Transmitter Antenna works best on teams that rely less on specific spell outcomes and more on melee or weapon damage, where the scramble hurts enemies more than it hurts you. In Bionic or Cyborg set compositions, equipping it alongside Signal Amplifier and Receiver Antenna creates a robot-themed set with strong cross-synergies. The 2 mana reduction alone can be powerful for high-cost spell builds, but the spell scramble is a liability for carefully constructed caster teams.
