Modern builds require modern tools.

Path of Mastery plans your Path of Exile 1 build with a full calculation engine, then stays with you through the league: a leveling guide made from it, a loot filter written for it, and a record of what every map earned.

Free to use. Pro adds the AI features.

Path of Mastery with a Cyclone Slayer build open: the passive tree in the centre and the stat sidebar on the left showing 2.08M combined DPS and 57.7k effective hit pool.

Plan

Plan with numbers, not guesses.

Every damage, defence and max-hit figure comes from a full calculation engine running on your own machine. Change a node, a gem or an item and the numbers move as you click.

Short on points? Optimize pathing finds a cheaper way through the tree to the same notables.

How build planning works

Ask Pro

Ask about the build in front of you.

The assistant reads your tree, items and gems before it answers. Ask why your chaos resistance is low or what to swap for more damage, and it brings back the change as a card you can accept or dismiss.

What the assistant can do
The assistant panel answering 'How is my build doing?' with a card for Cyclone Slayer: 2.08M combined DPS, 57.7k effective HP, 4,988 life, capped elemental resistances as a strength and low chaos resistance as a weakness, and a Fix weak points button.

Level

Level with a guide made from your build.

The Leveling tab turns your build into a route through the campaign: the gems to pick up, the tree to use at each checkpoint, and steps that tick themselves off from the game log as you play.

Journey is next: it follows your character live and tells you the next move while you play. Coming soon

Leveling and Journey

Gear up

A loot filter written for your build.

Path of Mastery reads your class, main skill and gear, then writes a filter in stages from Act 1 to red maps. Your bases, uniques and gems stand out; weapon classes your build never uses go quiet. One click writes it to your game folder.

How the build filter works
The build filter preview for a Pathfinder using Poisonous Concoction at the early-maps stage: 35 rules shown, such as the build's uniques and skill gems, and 7 hidden, such as weapon classes the build never uses.

Farm

See what an hour of mapping earned.

Wealth follows your stash value over the league, splits your time into sessions, and shows divines per hour for each activity, with the biggest movers in your stash and a bulk board for trades.

Wealth tracking
The Wealth overview: net worth of 113.0 divines, up 76.3 this week, a seven-day chart, rate by activity, movers in the stash over 24 hours and a breakdown by uniques, currency, scarabs and fragments.

Everything that runs on code is free.

The engine, every build tool, tree optimization, the build filter, the leveling guide, wealth tracking and Journey cost nothing. Pro is the AI: the assistant, Jev decisions on close calls, and explanations of what to change and why.
