Exact AION Classic equipment rules behind the gear comparison

To compare two sets of gear honestly, the site needs the same rules the game uses. We are reading them from the AION Classic 5.0 client itself: which slots each item fits, which classes can wear it, how stats add up and in what order, set bonus thresholds, upgrades and armsfusion.

Every rule will carry its place in the game files, and anything we cannot confirm is marked as not available instead of being guessed or counted as zero. A real worked example checked against the game will prove the rules before the comparison tool goes live.

For you, this means stat differences you can trust, with an explanation for each change instead of a generic sum.
