sun ribbion
none, make it love you a bunch
First, you have to have defeated Darkrai. Second, you need to equip riolu with a sun ribbon, and take it to the spring where you evolve pokemon. Then it will evolve into lucario.
easy depending on your Pokemon it may need an item for example for riolu to evolve you need an item [the place is the luminous spring].and you need to recruit palkia!
All I know is that you need to use an item to evolve Rioulu
you need a sun ribbon and its IQ needs to be 1 star
You need to have his IQ at 1 star or more AND you need a sun ribbon.
you need to have explorers of the sky and answer the questions correctly to be riolu
You need the Link Cable in your bag and if it requires an additional item to evolve then that item too then you can evolve it in the Luminous Spring.
make riolu consume solar ribbon when the voice asks if ya need an item to evolve
Any Pokemon that has an evolution can evolve. Some Pokemon may need some sort of item like a Thunderstone to evolve, though.
riolu dosent need a stone just raise it intell its lv46 that's what level mine evolved at.
riolu doesnt evolve with lv im afraid. like eevee needs maximum happiness in the day to evolve into espeon you need to lv up at maximum happiness in the day to evelve riolu into lucario. i know its anoying when that happens!
