Actually, I beg to differ. They are suppose to be remembered, you should get it back once you are Palladin. You also get emergency care for free if you had not gotten it before.
U keep first job quest skill (fatal blow + hp recorvery while moving + auto berserk)
But you will lose second job quest skill (Shrink)
Thats it for when u will reborn your crusader. However, you will regain ur first job quest skills when u will have the job lvl of swordsman that was required to start the quest.
