What would you add to Heroes? (creative ideas only!)

Hmm... well, if elves revered deer that much, they probably wouldn't make headgear out of them))) Even from those who died of natural causes.
P.S. I understand, thanks for the explanation.

Most likely, the deer is their totem animal; they identify with the deer. It's quite possible that they transform into deer for their own purposes. Who would suspect a deer of doing something bad? And then it immediately turns into an elf and shoots an arrow... And the high druids wear a wolf helmet, thereby transforming into a wolf. Orcish shamans might transform into a bear.
