You need to find 2 Riolus and bring them to the light barrier where you fought with Ice's Pokemon. Then press "A" in front of the barrier.
You don't. You have to do it yourself.
capture Lucario in the almia castle
Lucario is at the Almia Castle and guards the Blue Gem.
You get riolu when you go to Almia Castle to search for the blue gem.
first you need 2 rilous and bring them to the place where you fought frostlass then enter the light barrier.
To get through that blue energy wall in Pokemon Ranger Shadows of Almia in the Almia castle, capture Froslass as a boss, have 2 Riolu's in the party and use it's power.
yiu can find an electrode in pultown by a blue building
After you defeat lucario and obtain the blue gem, a quest will be avalible to save a piplup from a pokemon.
If you're asking about the blue crystal in Pokemon Ranger Shadows of Almia, then it's at the top of Almia Castle. To get there you surf with a Floatzel through Crysta Cave then go through Hia Valley then surf through the icy lake and then go all the way to the top of the castle and fight Lucario and then you'll have it.
He's in Almia Castle, near where the blue Tears of Princes was. For 'Murph's Disappearing Act.', unless that wasn't what your asking, if your asking 'Where is Murph so I can do his quest' He's in the first room on the second floor of the Ranger Union. Hope this helps.
free all the Pokemon of their confusion by destroying all the giregimoes in pueltown; greeen giregimoes- growithe (caught when red giregimoe has been destroyed) blue giregimoes- voltorb or elecid (found in pueltown) red giregimoes; biabarel (found in forest beow pueltown)
Go to the next room. Ice mentioned a strong Pokemon ahead guarding the Blue Gem. It happens to be Lucario. After you capture it, then a warp hole will appear, allowing you to get back to the entrance.
capture riolu. they are beyond the other doors that are there. be careful cause there will be a lucario as a boss.
It is a event (its called the blue sphere and its also Pokemon Ranger Guardian Signs)
