When melding familiars of different species, the desired species may NOT be preserved.
This is NOT clear from the in-game description of melding.
Earlier tonight, I melded a previously melded Duskprowler with a previously melded Varog. Instead of a Duskprowler, I ended up with a Varog, which completely upsets the synergy between my character and her companion.
If I had know the meld could change my companion’s species, I would NOT have melded.
Familiars are a great addition to the game, but, at the very least, the in-game description of melding needs to be updated to be clear about what happens/could happen when different species are melded.
