Eh, why not both.
Its between the two of them anyway for the former, but since theyre both up there, may as well look at gameplay wise.
Also, thats the thing about shadowgift, I really like dark magic(WTB NECROMANCER SCROLL DLC THANKS - It could totally be canon with risen), and besides nosferatu tanking, Waste/Ruin are pretty cool, but I wonder if/what I would go in place of sorc (Sage or GM)
