There are not many Deeplings Elite among Fiehonja. I decided to present them also with Deepling Tyrans sice it might be helpful while doing bestiary. As we know we have to kill 1000 Deeplings Elite and 2500 Deeplings Tyrant, so it's worth to not skip the Tyrants while killing Elites.
Deepling Elite is marked on maps as PINK
Deepling Tyrant is marked on maps as GREEN
From my own experience: if you're interested in completing bestiary on Deeplings Elite (as well as on Deeplings Tyrant) I suggest to focus on levels -3 and -4.
