Dark Mage class series

The Dark Mage class series is a special class series that is only achievable when the Tomegathericon is equipped to any character. Consequently, this is one of only three class series that can be learned by any Adept. This class also features at least one Psynergy from each element, though the majority are Venus and Mars.

It is important to note that there is also a class in the Medium class series titled Dark Mage, but it is very different from this class series.

Psynergy Setup
There are perennial rumors that Dullahan must first be defeated before the Necromage can use Call Dullahan. EDIT This is not true, it is possible to cast Call Dullahan from the moment when one of your characters can equip 9 Djinn.
