Fair warning about Drooburt during this Lunar New Year festival, the cheating little scamp. For every 1000 luck you give him you progress an achievement/get a small reward. However, any luck you give him in excess of the current tally is lost - i.e. it won't roll over to the next one. So, for example, if you have 900/1000 given to him and hand him a Legendary Essence (500 luck) he keeps the change, and you are still at 0/1000 for the next one.
This obviously won't bother those players who have obscene amounts of luck but for those of us who still have points to gain it's a little irritating. Anyway, festival is over soon but maybe they'll fix it for next year. Until then, exact change only for the thieving quaggan!
(I'm not sure if the food pigs have the same issue because I was more careful with them once I'd dealt with Drooburt, but I wouldn't be surprised. Be careful!)
