I've been curious about this for a while as someone who has never played Tera. I've seen all the other animal ear types for the Elins, bunny, fox, cat etc. Which type of Elin is this bat head winged girl though? Some kind of devil or succubus type? Then there is the Elin in post #1763061, mouse ears?

I've also seen an Elin in an MMD with larger horns than the 'sheep' Elins.

There are 12 hairstyles, each with different ears and tails, but they aren't tied to certain classes or specific elin archetypes in the game itself - they're just cosmetic. When you pick your hair, the ears and tail don't come separately and you can't mix or match.

This elin's animal counterpart is probably akin to a qilin and the elin in your linked post is probably a lion. Both are new to the reaper class update and are way more ambiguous than the older hairstyles. About the larger-horned elin.. I wouldn't know without seeing it. Probably just artistic license.

Thanks for the info, would love to try playing the game myself but just never have the time plus my comp is no where near powerful enough to ever run it.

Here is the Elin mmd with large horned Elin if you want check it out.

Oh! That's a cosmetic headgear, not part of the elin herself. :)
