Quest Item dropped from monsters

[Majestrix]

Hello, need some help on where to get these items 'cause the quest tab wasn't specific on where to go:

Healthy Drink Powder
Bug Repellant Coil
Pale Colored Scale
Decorative Legs
Straw Rope
Bamboo Rotocoptor
Twilight Melancholy
Lotus?/Locust? Spoon - For the 25% gold Magatama

Also, any idea on what dungeon to grind on when you're lv.25+?
I like to solo, but Byakkou is pretty slow on Hell.

Healthy Drink Powder = Grass Stickies, at Onigashima Fields, Abou Forest, Daiku Cave (Hard to get)
Bug Repellant Coil = ^same as that (Semi rare, but is easier than the powder to get)
Pale Colored Scale = Tiamat, Sakurajima Depths.
Decorative Legs = The Big Boss Bronze Statue, the one at Ooikazuchi Caverns.
Straw Rope = Kubire Oni, They can be found at either Nakisawame Caverns at Izumo or Well of Virtue at Kyoto.
Ramboo Rotocoptor = Benggara, the yellow version of Morizou. Common at Izumo Fields.
Twilight Melancholy = Sunset Stickies, at Sakurajima Depths, Cave of Screams, Three deity Cavern.
Lotus Spoon = Swamp Stickies, at Seiryuu Grotto.

Tbh, if you really need to level, never go Hell if you plan to solo. Unless you can dish out instant kill damage and killing a lot in a single sweep. Go do Hard runs, it will be easier and faster. Since you are at lvl 25, have you tried leveling at either Honomusubi or Nakisawame caverns? Although I don't really get why you would solo on a game that promotes (at the moment) going in dungeons in teams.
