Drake and laurel gobbue mounts are gained from the new beastmen quests (with reputation points raised by completing those quests - the beastmen vendors sell the mounts). As well, there is also the new 'gilded' magitek armour (it's the same as the one you get by completing the main scenario, only painted gold), which is an achievement reward (I can't remember the exact achievement required though). And finally the behemoth mount is a veteran reward from getting 270 days of subscription (at the moment this is very hard to actually get however).
