The rusty door to the perfection lab in metchi town won’t open, do I have to do anything specific before that?
Reukra already said he was retiring to somewhere quiet when we first meet the zygarde hippy, I’ve caught zygarde, beat Taen, seen the cutscene where he gives Reukra whatever it is that he got in no man’s land and leaves to another region, caught volcanion, cured Damian, and beat the holon story. Have I missed anything?
Edit: and caught groudon and kyogre too.
Edit 2: found a note in the perfection base. I’ll get through that quest and then try the lab again!
The Reukra scene shows up after you beat zygarde in the dragon ruins and Taen leaves. You get to holon through the train in suntouched city after you get a call from the scientists club.
It’s not that poke ball, I don’t know how to get that one either. The one with the note is where the cutscene takes place (same place where you first meet the zygarde hippy and his friends the protesters)
After you beat Red and become the new augur you get a call saying someone in Deyraan town has a problem (or the king might tell you that himself, I can’t remember). When you get there go to mount rose, and in the infernal cult headquarters you’ll get the double battle with heatran and volcanion.
You can also catch groudon there, which I did before the double battle, but I’m not sure if you need to catch groudon first or not. I got lost and wandered about until I found groudon (deep inside the cave behind the magma waterfall), and when I finally got out with an escape rope I appeared right next to volcanion & heatran.
I can’t remember if you get a call or if the king just says he knows someone in Deyraan town is having trouble, so maybe you don’t need to wait for the call. Head there and check just in case, the guy should appear right at the entrance of mount rose.
Good luck!
