Requirements for the Third Bird of your choice:

 

▪︎︎100× Gems depending on the bird's type -> possible

▪︎150+ IVs for the Pokemon -> tier 7-8 pokemon with +150 iv almost imposible

▪︎335+ Evolution Data -> hard but posible

▪︎600+ Caught Data -> posible

 

tier 7-8 poke with +150 IV is so hard to find. Some people can fullfill this condition with luck but i think all players need more chance. My wish is drop that IV limit to +130.

The entire quest in general needs to be revamped. It's too long and too difficult for one of the weakest legend trio in the game.

 

It's the freakin' bird trio, not Xerneas, Yveltal, and Zygarde Complete.

Even 140 IV for 3rd Bird would be ok, ive found like 10+ magbys in range fo 140-148 IV... None 150 + yet.. That's really impossible for a dex entry legend...
