A Path of Exile tool designed to predict and simulate the outcome of using Legion Jewels to modify passive skills within a character’s skill tree, focusing on Notable and Keystone transformations. These calculators often allow the user to input a jewel name and seed number to display the resulting skill tree alterations. This enables players to plan their character builds effectively by understanding which passive skills will be changed, and into what.
These tools are valuable to players aiming to optimize their characters. The ability to preview potential passive skill changes mitigates the significant cost and time investment associated with acquiring and experimenting with different jewels. Further, it provides historical context and collective player knowledge regarding specific jewel and seed combinations, allowing for informed decision-making about character builds, and increasing the economic efficiency of jewel trading within the game.
