Elden Router

A routing tool for Elden Ring.

What is this?

Elden Ring is an open-world video game created by FromSoftware. This tool finds the shortest path to a particular item. The user can customize whether they want to have to beat a boss to get it, or whether they want to use glitches. Elden Ring is a pretty large game, and there are many ways to get to different regions especially if you factor in glitches. That's where this tool comes in.

How does it work?

This tool uses graph theory. Locations in the world are nodes, and I use edges customized with certain attributes to connect them. Edge have attributes such as boss_required, glitch_required, or items_required.

First, the tool filters out all edges that don't conform to the user's selection. If the user disallows glitches, the tool filters all edges that require a glitch. Then, the tool runs the dijkstra graph algorithm to find the shortest path.

Example Output

// item, allowBosses, allowGlitches, itemsAcquired
getPathToItem(items.RIVERS_OF_BLOOD, false, true, [
    "DECTUS_MEDALLION_1",
    "DECTUS_MEDALLION_2",
])

        ]
    },
    {

                    "DECTUS_MEDALLION_2"
                ]
            }
        ]
