I was originally seriously thinking about this, but then I forgot about this topic, and went through Mt. Moon. I have to start reseting about 50 times to get Nuggets from Nugget Bridge so I can buy a ton of stuff at the Game Corner (Dratini, Ice Beam, Flame Thrower, T-Bolt) and to have plenty of money to buy proteins because my Charmeleon's attack stat is the lowest.
It's hasty and extremely fast, and I don't care about DVs. But I do care about nature...
Anyway, I found out that the Old Rod can be obtained in Vermilion so I decided it's okay. I think there's some water in Vermilion that's accessable so I'll just fish for 'karp there and train it on the SS Anne.
Thanks to both of you, but this can be locked.
