((One week wait to do again.))
Go to Lost Ruins 1 (46, 55), meet with Jaryn. He will explain about the Fire Serpent and ask if you have seen it(here you have 2 options "Yes I have." or "No, not yet...") choose "No, not yet...". Here he will explain that he would love to see it but he cannot because his skin is too delicate (another 2 options "Sounds like fun!" or "Nah, I can't take the heat!") choose "Sounds like fun!". Then he will say that you need to capture his baby Fire Serpents (Stunned Fire Worms ()) . He is unsure of how many are needed to summon the creature (20 Stunned fire worms per person). Follow the dirt path to get summoned to kill the Fire Serpent. After killing the boss return to Jaryn. He says to wait ((One week)) a bit while he examines the skin. Don't wait too long or the quest will restart. Return to him after waiting and he asks for 3 Shinguards () (Obtained from Canals) and 5 Gold Bars () (Money) and he will give you Fire Serpent Boots (). He will also reward you with 10k Ability and 10m Experience Points along with a Legend Mark.
