ToME: the Tales of Maj'Eyal

Turning into a shadowy wraith and walking through walls doesn't seem to fit the theme of Shadowflame to me.
So I suggest changing this talent to combination of Burrow and Mucus.
When active you would be able to melt your way through walls and you would leave a trail of Shadowflame behind you.
If you have Flame of Uhr'Rok active, the trail becomes a radius 1 spread.

Would need a new name, but I can't think of one at the moment.

I like the change, assuming we want to keep the general talent the same.

As for changing the name from Wraithform... perhaps something as simple as Shadow form?
If not, maybe Dark Trail? Haunting Presence?
