Plan the whole build with every number live.

Tree, skills, items and config in one window, with a calculation engine that updates as you click. When you want a second opinion, the assistant reads the same build you are looking at.

A full engine behind every number

Damage, defences, max hit per element, mana and life all come from a complete calculation engine running on your computer. There is no estimate step and no server to wait for.

  • Every stat on the sidebar opens into its breakdown in Calcs.
  • Optimize pathing finds a shorter route to the same notables, free.
  • Older tree versions convert to the current one in a click.

Ask the assistant Pro

The assistant reads your tree, items, gems and config before it answers, so its advice fits the build in front of it. It brings back changes as cards you accept or dismiss, and accepted changes apply to the build.

  • Ask why a stat is low, what to swap for more damage, or how to cap a resistance.
  • Jev decisions settle close calls, like which of two items or gems is the better setup.
  • Every suggestion comes with the reason in plain words.
  • Runs on your own Claude or ChatGPT sign-in.
