I couldn’t verify a game-specific “path grid” mechanic for Roblox Eternal Secrets from reliable public sources, but the most likely meaning is a pathfinding grid or grid-based movement system. In that case, the usual way to “get” it is to create or enable a grid in the game/editor and then use pathfinding logic to move across adjacent tiles.

What this usually means

A grid path system works by treating the map as connected squares or nodes, then checking which neighboring squares are walkable and building a route from start to finish. Roblox’s own pathfinding documentation describes pathfinding as moving an agent along a logical path to a destination, which is the standard foundation for this kind of system.

How to get it in practice

  1. Check whether the game has a built-in build or placement mode that exposes grid snapping or path placement.
  2. If you are making it yourself in Roblox Studio, create a grid of tiles or nodes and mark blocked spaces.
  3. Use pathfinding logic to link walkable neighbors and generate the route, then move the character or object along that route.

If you meant a game feature

If “Eternal Secrets” has a hidden item, upgrade, or unlock called “path grid,” that would likely be game-specific and not documented in the sources I found. The closest public references I found were general Roblox pathfinding material, not an Eternal Secrets guide.

Best next step

The fastest reliable answer would come from the game’s own community page, Discord, or update notes, because this looks like a niche in-game term rather than a standard Roblox feature.
