I am new to MS (Like i tried to get into it tons of time but just recently started back up)
I am doing a mushroom kingdom quest thing and there is this blocked portal and it says I need a Poison Spore, so I looked online and i get it from Poison Mushrooms, right by the portal.
BUT i have been farming them for like half hour and have not found one. Am i really unlucky or really stupid?

you do the quest for the guy and he gives a potion you have to use to get through it had a point of frustration there also

Also once you have the potion you may need to try jumping in a few times. It used to be a glitch and tell you that you need the potion even though you already have it.

thats a neat dungeon but ya that part is kinda buggy.

at least a year ago when i did it >_<

It bugged out for me as well. I changed channels and it worked, though.

just do the quest, the other method only works once i believe
