Wow that is a little low.
I guess I'll have to obtain a second Life Orb from Heartgold.
Where do you find the Life Orb? I read it is in the "upper left" of the Ruins of Alph but that description confuses me. Are there more than one underground chamber in the ruins or what? Or are they talking about the overworld, because even then I haven't found it.
There are four chambers you can enter in the Ruins of Alph, one is accessible straight away, the second one i think you need surf to get to. The other two however, are only accessible from Union Cave (you need Surf for these as well). At the back it has writing in "Unown language". You need Ho-oh to open this particular one.
