Melomach

CREATURE 13

Melomachs are massive, vaguely humanoid elementals composed of metal debris. They take great pride in decorating and augmenting their metallic bodies with haphazardly placed spikes, blades, humanoid or bestial skulls, and other similar adornments, the more ostentatious the better. When two melomachs meet, the resulting contests of physical might and vocal prowess can last for days, often leaving the landscape ravaged for miles in every direction.

As long as it is immobile, the elemental can't be forcibly moved or knocked Prone. If it takes a move action, it loses this immunity until the start of its next turn.

Lightning Punch

The melomach makes a fist Strike, then makes a lightning Strike against a different creature within 120 feet of the fist Strike's target. Both Strikes count toward the melomach's multiple attack penalty, but it doesn't increase until after both attacks are made.

Rhythmic Stomp (emotion, mental, primal)

Frequency once per round

Effect The melomach's footsteps raise a clanging sound through their body to create a brief musical phrase. The melomach Strides, then generates the effect of one of the following bard composition cantrips at 7th rank: Allegro, Dirge of Doom (adds the fear trait), or Triple Time.

Scream (primal, sonic)

The melomach unleashes a guttural, ear-piercing wail. All creatures in a 120-foot cone take 7d12 sonic damage with a DC 32 Fortitude save.

The melomach can't Scream again for 1d4 rounds.
