The problem to solve

The Path of Exile 2 Atlas contains many different areas, mechanics and strategies.

Depending on the biome, I wanted a quick way to remember certain things before entering the area: an objective to complete first, a mechanic to leave until the end, a particular danger or simply a note related to my current strategy.

Instead of keeping those notes outside the game, I built a small overlay capable of automatically displaying the right reminder at the right time.

Biome detection

Before placing tablets, I simply hover the mouse over an area of the Atlas.

The helper analyses the information displayed on screen and identifies the biome by its name. Multiple OCR aliases can be configured for each biome to make detection more tolerant.

Once the biome is recognised, the associated message is displayed directly at the top of the game.

Fully customisable reminders

Each biome can have its own message made up of several lines and colours.

For example:

  • remember a mechanic that should be completed last;
  • highlight a particular danger;
  • indicate an order to follow;
  • display information related to a specific strategy.

The tool also allows the font, size, bold style, overlay position, background and opacity to be configured.

The goal was simply to have the right information visible at the right time without interrupting the game to check notes elsewhere.
