The article Orb of Rebirth lists everything that you lose: level, attribute points, gold, XP, mana, and equipment are the major ones. You lose all your equipment but you can buy it back for gold in the Rewards column. You do have to be the correct class to buy it back, though. I'd bought some non-Warrior gear in the Seasonal Shop, so I have to change classes to get it back.

You definitely keep your drops, quest scrolls, special items, and achievements. The quest scrolls that are level-dependent will lock again until you reach the level where they will open.
