1. Getting to 3rd job on my first ever character, a thunder breaker, back when I was a kid.
I found it so amazing how they threw around green sharks and transformed into stylish, blue dudes with spiky hair.
I even made a youtube video showcasing the skills they had (with terrible choices of music of course...).
I never made it to level 120 though, the level cap back then for cygnus knights.
2. Playing a buccaneer.
I was such a big fan of the transformation skill that thunder breakers had, that I had to play a buccaneer, except this time, I made the new character into a female character. The female sprites for the transformation and super transformation skills were really cool too, with the ponytail and all.
I also loved how buccaneers slid around backwards while elbowing monsters in the faces.
3. Reaching 4th job on a fire poison mage.
Again, I loved the skills they had.
I loved how they stared down enemies to death with their old paralyze skill animation and how they summoned frogs to belch out toxic clouds.
I loved the little "witch" theme fire poison mages had back then.
