So here we go… I litteraly explored every piece of the Mount Rose and I can’t find a way to get Delta Phantump. Since the wiki is not updated at the time, I ask you : where could it be ?
P.S. : I found the Hidden Grotto, but all I found in was Charmander, Deino, Swablu, Doduo & items in 100+ attempts.
its in a hidden grotto. you need to soft reset until delta phantump appears
Alright, I’ll keep spamming then…
Edit: I ragequit. Either I’m the unluckiest man on earth or the information is false
Edit 2: Nevermind, I was searching in the wrong Hidden Grotto. My bad !! 
where’s the hidden grotto?
When you enter Mount Rose, climb the stairs, then move in the upper part until you find the scientist.
It’s there.
