Also you can attack it's chest to deal crit. damage. Though potentially you might get crushed. But as far as I know, it's the only way to kill it with swords.
Tried this many times, and worked 95% of the time (I only count off the 2 times when I was hunting with true noobs that kept hitting the gong at the wrong time).
It's better than lao shan lung that walks at 2 miles per hour, and who's only attacks are accidentaly stepping on you and crushing its brain against a wall. It may get boring if you've done it 5 times in a row, or if your doing the low event quest.
