SPIDER bears and SPIDER dragons!
I would most definitely pay to have spider dragons and all sorts of mad imagination creatures come to life in this game.
Although, mentioning dragon training as a type of magic or 'specialization' sounds bloody awesome. Flying mounts? Yes, please.
But, in another reference, Mother of Dragons sounds better than Mother of Bears (still sounds good though). While, Mother of Wolves reminds me of Roman mythology.
This could also be a good expansion on the golem trait, allowing the hero to have a potential to specialize in creating, managing and empowering golems.
Which leads me down the winding road of; why not have specializations for all types of soldiers? There could be a defender only potential trait which would allow him to increase the initiative or damage of other shield wielding units. Also, perhaps an archer specialization for the assassin or warrior which allows them to enhance the initiative or allows for the use of a 'volley' ability when 3 or more bow units are in a group.
