Monster unlocking

Hi, i saw a youtuber with a team of 2 trait from 2 creatures are Plague Soothayer and Dryad ( i searched from the wiki) but still cannot find them in the game. Is there any secret location? Im currently at realm 135 and max level 465

Dryads are in Shallan’s god shop (fae lands), Plague Doctors are in 4080’s god shop (Forgotten Lab)
