The first skill of Viking Magic is stacking just like Mage Mana Maile of the Warlockery skill line, just go up or down a starcase and you can put another stack on. Screenies: Normal: 5 stack: I too have tested with Hand of Belimawr, but didn't work. PS: The save file is still from before CotWL, but I got a screenie with a new char after CotWL: Well, It's not as exploitable as Mana Maile, but on easy and 4 mana regen you can easly have 5 stacks and 1 of belimawr (it's better) without losing any mana. o/
~sigh~ Yes, they know. It's not just that particular skill either, as you had mentioned yourself. The problem is that something broke in the code for controlling stack size limits, and thus things that aren't supposed to stack sometimes do. They are already working on it. That being said, thank you for the notification. It was well-fleshed out, so even though it wasn't as useful as it could've been, props are to be given to you for trying to be helpful.
