Absol is very easy to find, You just have to play the pokémon talk radioshow on your pokégear radio. The tune plays on Wednsday. I caught a absol myself in the union cave at level 6. It took me about 10 minutes to get one. You can indeed catch it in all the caves that are mentioned above but only if you play that radio tune.
Their is more than one way to get an absol and it does not have to be on a wed rarly you will find it in the ice cave by the last gym leader in the johto region no joke I caught one myself but I you want to wait till wed thats fine but just keep it in mind that absol is their in the cave
Bulbapedia Says its in Slowpoke Well, Union Cave, Mt. Mortar, Dark Cave, Whirl Islands, Mt. Silver, Ice Path, Ragged Cliff Gate, Diglett's Cave, Mt. Moon, Cerulean Cave, Rock Tunnel, Seafoam Islands, Victory Road, Tohjo Falls only thing is It's a rare Pokemon so, might take some time trying to find it... Keep trying and maybe or most likely you'll find it I found it once in Victory Road but failed to catch it Since I was informed that Absol was in Victory road It took me 2 months to finally find it :/
You can get Absol in any cave as long as it's Wednesday and your radio is playing the Hoenn sound and no there does not have to be a certain time of day.
I don't know, but the map blinks red, instead of green! So that means you have to find it some other way than just finding it when you're walking... ???
You can find it in soulsilver, you just need Hoenn Sound to be playing in order for it to appear in the first place. Only place I know Absol for sure is in is Dark Cave.
No matter what, I can't get an Absol. I went to union cave, on a wed. (altered setting in DS) and I played the radio talk show, but I got nothing. The tune didn't sound any different either. Should I have not altered my settings? Or am I missing something?
I really need an absol (because I need 1 more dark pokemon I'm a dark trainer) and I know Wednesday but is there a specific time because the sound isn't different
