Uhm i've noticed that there are two symbols that may or may not be ripped from thaumcraft? It appears the Minotaur and Spirit pets have the exact same icons as Pride from thaumcraft 4.2 and or Mythus from Thaumcraft 6 while the spirit has the same as the Spiritus icon

All of the item icons in this game were pulled from a free set made by Lorc. I really like their style.
