I few days ago i finally decided to level discord (after 2 years here lol), so i just followed the guide on wiki, as i always do, but to my surprise the animals-gains ratio was far from accurate, at least for the experience i was having (i've known quite a few players who differed greatly on what animals to discord at what level). Anyways, i thought it'd be a good idea to post the sequence of monsters/animals that took me from 30 to 120, in case it works for somebody else. Hope it comes in handy for other fellow excelsorians. The numbers are merely orientative (tho fairly accurate). just go down the list when the gains are not regular.30-40ish: grizzly bears
40-50ish: frenzied ostards
50-60ish:skorpions
60-80ish:giant beetles
80-93.9:hyrius
93.9-120:serpentine dragon
Now, up to giant beetles, those can be found at moonglow zoo. For Hyrius, i used one located West and a little South from Mt. Sho Castle, in tokuno (available from world tele). As for Serpentine Dragons, go to Serpentine Passage, Ilshenar (i know xD pretty obvious), located in a cave which is accesed through a dirt road leaving the city of Mistas by the north (easily located using a map)
oh,also: grizlly bears, hyrius and serp. dragons wont attack u if u dont attack them first, so u can discord them in peace. frenzied ostards,skorpions and giant beetles can be discorded from behind the fence,so no problem either
well,hope this works for you, and thank you for your time!
cheers,
