Just upgrade pokke farm so you have the best mooshroom tree.Then just do those crappy gathering quests and just keep going to the farm and you'll have them in no time
tbh i struggled to find the thunderbugs
lol . With the dw longsword i tried to kill the rathalos but it always seems to need sharpening !!! Anyway when you have the dragonwood longsword you can upgrade to ' fanatic dragonwood long sword' which is very powerful when at a low rank....BUT you need dragonmoss+ and dragonwood+
