The Phase-Lock Webbing
A shimmering, translucent lattice of spider silk that vibrates at a frequency that straddles the border between the Material and Ethereal planes. It appears almost invisible until light hits it at a specific angle.

Defenses
Detection
“Fine, violet-tinted strands that hum softly and seem to fade in and out of existence. Small, frozen motes of dust are trapped within its structure.”
Standard Engagement
The hazard is triggered when a Medium or larger creature enters the 10-foot-square area covered by the webs.
None (Simple Hazard)
The webbing regrows its dimensional anchors 24 hours after being destroyed unless the area is hallowed or cleared with a Wish spell.
When triggered, the creature must succeed on a DC 14 Dexterity saving throw or become restrained by the webbing. While restrained, the creature takes 2d10 force damage at the start of each of its turns as its body is pulled between planes.
A creature restrained by the webbing cannot use any form of planar travel, including the Etherealness spell, Misty Step, or Dimension Door, unless it succeeds on a DC 14 Charisma saving throw first.
Any creature that hits the webbing with a melee attack using a metal weapon must succeed on a DC 12 Constitution saving throw or take 1d6 thunder damage from the high-frequency vibrations.
If the four corners of the 10-foot square (the anchors) are hit with 5 or more fire damage simultaneously, the entire web collapses and the trap is neutralized.
