Elder White Tiger

I Have seen an elder white tiger in Melandru's Hope! i cant cap it in enough time because the boss caps it before me!!!! Even before i get in range to interupt it, he caps it! Are there any suggestions on how to cap the elder white tiger? Maybe there is another place where i can cap it? Any help at all will be great! In-game name - S P I R I T W I N D

There's a thread at Canthan Explorers' League session talking about this:-
