Learn how to set up the River Styx Phantasmal Filter for glowing rivers, spectral streams, and dramatic negative space on your gaming table.

Quick answer

Place the River Styx Phantasmal Filter directly on your table for a dark river effect, or layer it over a Dwarven Forge Light Panel for a glowing spectral stream. Use it to fill negative space without adding bulky terrain.

Why use a translucent filter for table coverage

The River Styx Phantasmal Filter is an 8-inch translucent sheet designed to cover empty table space with visual drama. Unlike solid terrain pieces, it lets you create depth and atmosphere without blocking line of sight or adding height to the play area. This makes it ideal for rivers, chasms, or magical pools where you want the table surface to feel alive.

One trade-off: the filter works best in dim or controlled lighting. In bright overhead light, the translucent effect is less dramatic. Plan your table lighting to get the most out of the filter's glow.

How to set up the River Styx Phantasmal Filter

1. Choose your table location: Identify the negative space on your table where you want a river, stream, or magical pool. The filter covers an 8-inch area, so measure your gap to ensure it fits without overlapping terrain pieces. Common mistake: placing the filter where it overlaps dungeon walls or scatter terrain, breaking the visual flow.
2. Decide on the effect type: For a dark river effect, place the filter directly on the table surface with no light underneath. For a glowing spectral stream, position a Dwarven Forge Light Panel beneath the filter before placing it. Checkpoint: test both looks before committing to a final placement.
3. Position and align the filter: Lay the filter flat on the table or over the light panel. Rotate it to match the flow direction of your terrain layout. Press gently to avoid air bubbles if using a light panel. Common mistake: creasing the filter by pressing too hard. Handle it by the edges.
4. Adjust table lighting: Dim room lights or use directional table lamps to reduce glare and enhance the filter's translucence. If using a light panel, keep room lights low to maximize the glow. Checkpoint: view the table from player eye level to confirm the effect reads clearly.
5. Secure for gameplay: The filter lies flat on its own, but if your table is tilted or players frequently lean over, place a thin terrain piece or token on the edges to hold it in place. Avoid adhesive that could damage the filter. Common mistake: using tape or glue that leaves residue. Weigh it down with scatter terrain instead.
