BDO - Eilton Daily Quests 30 Oxiterr Crystal in 15 minutes 

Having prepped turn in quests, I have 1 character sitting in Eilton ready to do this everyday for free Superior Cooking Utensil or Alchemy Tool
Items to prep
Snowfield Cedar Logs,
Snowfield Cedar Sap,
Jade,
Apple, Banana, Strawberry,
Citron Cider.
Something Different Every Day Quest - You will get free food from him that you can reuse to hand in infinitly. you use 1 and he gives you 2.
I suggest Premaking:
- Mesima Chicken Soup
- Pickled Citron and Onions
As The Reward
Grab the Eilton Sandwich, Fruit Sherbet, and Chanterelle Risotto
Or premake what ever is easiest for you.
you can skip what ever quests you want, i skipped the fishing quest because it could take 1 minute to who knows how long with bad rng.
This random route im doing completes 19/20 Eilton Quests and
5/26 Mountain of Eternal Winter.
Note - the Snowfield Cedar Plank you can prebuy, but you make 5 a day regardless from the quest "Think Outside The Citron Box"
So you can maybe just premake 5, for the turn in, and make them from the quest when you have it.
Extra Note - I know im bad at the game, and this could've been much shorter if I was actually good, this is an alt character.
Extra Extra Note - This video was for my brother to show it doesnt take hours. I took him along with me to show him the route and it took like 2 hours to show him everything and have him follow me around and then him buy everything he needs. He said "im not doing this **** every day this is taking forever" i told him its only 15 minutes without me dragging you around.
So I made this to prove it.
