Auto-Smelt Modulator
Automatically smelts whatever the Resonator generates.
Area of effect
Unlike the other modulators, Auto-Smelt has no area around itself. Instead, it checks whether the straight line between a crystal and its Resonator passes through the modulator's block — so it has to sit directly between the two, not just nearby.
Notes
The modulator glows and will ignite entities that stand on it, so place it somewhere out of the way of foot traffic.
