[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

The balancing factor of Spore is that very few can get it, and if you used Shroomish for every battle your other Pokemon would suffer.

Very true.  A Breloom definitely has the hardest time learning Spore out of all the mushrooms, that's for sure.  Foongus and Amoongus have a comparably hard time learning it too (disregarding Breloom's inability to learn Spore without learning it as a Shroomish), and Morelull and Shiinotic still take awhile to learn it, all things considered.

Paras and Parasect are terrifying, though.  They learn the move for 22 exp...(and they also learned it at level 17 in Gen 4!  Yikes! And even 25-30 in gen 1-3 is still the lowest level of any of them!)
