Game thinks I'm level 50

[Mountain1]

Hello. My main is a level 88 warrior and today I decided to level a Rogue. I did up to floor 10 of Palace of the Dead and swapped back to my Warrior and logged off. When I logged back in I lost every spell over level 50. They're not even in my spellbook. I've tried changing jobs, going to a new area, joining a guildhest, and reinstalled the game and nothing seems to fix it. Any help is appreciated, thanks.

Did you change by switching weapons directly? The warrior job crystal won't equip automatically, in which case you're not seeing your skills because you're not a warrior right now, just a guy with an axe.

Switching between jobs should be done via saved gearsets, not directly equipping weapons, as gearsets will equip all of your gear and your job crystal together. It's one of the buttons over your character portrait in the Character menu.

equip your job crystal :P

Since it's indicated that you're a level 88 marauder in your profile, I would say that you need to equip your job crystal. The skills will be right back.
