This is the thing I found when doing few hacking in with Codex on latest version (May-18 update). The vee's table has it also, but might need a bit offset adjustment.

This is per character block.
So your actual character level is "level displayed" - 1 which is the red box in the picture above, the hex address after it (the blue box) is the TOTAL amount of exp you have earned so far, meaning if you want to reduce your level then you also have to reduce the exp earned other than the level as well.
For the skills, it is in the colored box above it. Now here is the catch:
AoT2 has funny combination trick to determine what skills you equipped with the character. Each 4 byte addresses means a skill category (action / passive booster / stats / daily life / equipment added skills)
So for example, if you set the first block to 01 00 00 00 then the game determines you have only swoop attack equipped for action type, 02 00 00 00 means only spinning attack equipped while 03 00 00 00 means you have both swoop attack and spinning attack equipped.
In short: There is no exact per skill ID, but there is algorithm to determine the skills combinations wanted.
you can simply set all of them to FF FF FF FF which results in a lot of dummies or skills that you may not want to be equipped, simply you can just de-equip them from the skill menu (press "Tab" on there by default to switch between the available skill list and equipped list). You will also obtained some skills which suppose to be not exist like equipment set's stats boost "Agility +3" or "Health +5" or so the likes which results your stat goes over the cap. But those skills will be gone on the moment after game restart or equipment change.

ah my bad, actually follow the pict note I edited there, the blue box is the level, the amount of EXP gained is the address before it. The red box is amount of SP cap you have.
