Breath Weapons (Acid, Fire)

The ability to breathe either a gout of fire or a spray of acid.

Destruction Feeding

Rather than simply consuming meat, these hydras can destroy to feed. The most delicious and sustaining meals are the energies released when living things die, which they can absorb simply by being present. They can also consume any energies released when they enact their destructive powers.

Destruction Powers

These hydras are an incarnation of chaos and destruction. Destroying anything around them comes with natural ease, not from brute strength but from force of will.

Insubstantial Form

Although they appear solid, these hydras can will themselves into an insubstantial shape. Like a thick cloud of smoke or fog, they can barely be touched.

Natural Spellcaster

After reaching their first decade in age, the hydra begins to develop magical ability. The older they get, the more powerful they can become.

Shapeshifting

The ability to shapeshift into any other form, without limitation. (This could indeed mean shifting even more heads than their base 18, but they would not count as natural.)

Telepathy

The ability to communicate mind-to-mind.

Teleportation

The ability to teleport anywhere within sight or that can be strongly visualized in the mind.

Verbal Speech

The ability to communicate in spoken words.

Chaos calls sweetly and an intelligent mind sees it has the strength to use it.
