It is true what of the spells of lesser resistance has the rigor the shade for the 15%, it is not bad, but the escape spell frankly debatable for its effectiveness. While others have the right to physical and magical resistance of 5k, the black blade has the right to 1k5, in other words almost nothing.
The shadow spell just for a criticism bonus when we could make it so much more useful, for example, cancelling a spell on us would be interesting too.

And also the heal the big black dot of the class others have the right to fast heal spells the black blade has nothing just horrible in BG the shadow path frankly how do you want to play in PVP with that? especially in magic your nothing effective, the sipphonnant attack of no effect while other weapons, your crazy heal spells. When we see what the wizard or templar etc. is entitled to for this pleasure I really cry my nightblade that the devs seem to have a deep pleasure to kill...

There are some really shortened spells on the black blade so that could be more profound, other classes have the right to some really crazy stuff so why not the black blade too ???

For those who would find it disloyal to other classes, don't you think that other classes aren't disloyal enough, for example the templar who for me destroys pvp at the moment, or the wizard with crazy shields, crazy farts, crazy heal and crazy mobility?
