What Lurks at Midnight
4E wisps do have a "luring glow" ability (burst 20, +13 against Will, pulled 3 and dazed, save ends).
The immunity itself is just one of those weird traits that monsters sometimes have. It makes them into a sort of low-level golem, where the spellcasters have to let the martial types deal with the threat, unless they can figure out which spells to use.The 3rd edition wraith looks more like those things from Harry Potter.
As for wisps, I never got their magic immunity, even after reading their ecology. Why just those spells and not more poweful versions as well (like Dispel Evil or Holy Word). And does their immunity allow them to pass through Walls of Force?
Or... not.In many respects, wolves greatly resemble domesticated dogs.
I remember reading a Nordic legend about a monstrous wolf whose breath could freeze a man in place. In context, I thought it was freezing the person with fear, but perhaps the legend was rather more literal.As for Winter Wolves.... not sure the mythological context for them. I do know that in Pathfinder there are areas of Irrisen where they can assume human form.
