MHO guild chapter 16 final quest : again the flame queen

Hello everyone, i'm new to MHO and i'm stuck at the final quest of the 16th chapter, in which they ask to collect some sort of monsters drawings. i can collect 4 of them but the last one of chamelios i couldn't collect it, i got this message : 好像可以把某种石头镶嵌进去。 . if some one have an idea on how to clear the quest, i appreciate your help. thanks in advance.
