Dune's golden light dimmed steadily as they pressed forward, the radiance that had blazed like A sun reducing to something closer to candlelight.
His spectral form grew increasingly translucent, edges blurring until distinguishing his outline from the surrounding air required focused attention.
The great sword in his hands flickered, appearing and disappearing in rapid succession as if struggling to maintain existence.
A root-humanoid rushed from the left.
Dune's sword swept through it, but the shockwave barely traveled ten feet before dissipating completely. The construct shattered, but only from direct contact with the blade rather than the energy wave that had been obliterating enemies from hundreds of feet away.
Another attack came from above, a thick tendril dropping like a falling tree. Dune raised his blade to intercept, and the sword connected, cutting through wood, but his arms trembled from the impact.
No shockwave erupted.
