Logger Format Overview
This is intended to be a comprehensive guide to log lines for Lost Ark.
It is a work in progress.
Data on log lines is separated by vertical braces, i.e. |.
Log lines contain the hash of that line at the end.
These are all words used synonymously in this document to refer to an object in the game that can use abilities and has stats. This could be the player, Bahamut, Eos, a Striking Dummy.
Object ids are 8 byte identifiers used for all types of objects. These are represented as hex in the log file.
Skills are split into "skills" and "skill effects", as each skill has damage components. This is usually just a number appended to the base skill, i.e. Snipe is 28220 skill id, but when it does damage, it has multiple reported skill damages, such as 282201 and 282202. There is an english translation for all skill id's, but for skill effect id's, sometimes there's not an english translation.
Skill stages is not complete yet, needs more research.
You can use lostarkcodex.com to look up a particular skill.
This works for both NPCs and skills.
These are represented as decimal in the log file
