ServerExperienceModifierEvent

THE SERVER'S EXPERIENCE MULTIPLIERS, sent once and kept for the session. There is no request for it and no refresh - it arrives unprompted early on.

THE NUMBERS ARE OFFSET BY 100 - MOSTLY

Two of the values are percentages expressed as a multiplier over normal, and the client subtracts 100 from each before storing them. A wire value of 200 becomes a stored 100, i.e. "+100%". A third value is stored exactly as sent. If you read these raw and show them to a user you will overstate every bonus by 100 points.

WHICH IS WHICH IS NOT SETTLED, AND THIS RECORD DOES NOT PRETEND OTHERWISE. The reference build declares this message with a SINGLE field; the current one carries three the client actually reads. Only one canonical member name exists, so none of the three is named here - they keep their obfuscated names rather than being given a label by guesswork. What IS established is the shape: two offset-by-100 values and one raw one, all three stored into played-character state and read back from there.

A FOURTH DECLARED MEMBER IS PADDING and no dumped client has ever read it.

If you need one of these values specifically, capture it against a server whose rates you know - the transform above tells you how to interpret what you see.
