In the writings given by Vivec its written that Nerevarine can use the Tools in a wrong way, make them resonating the Heart in another manner than intended.
This is possible in the game? And, if this is possible, whats happen to the Nerevarine? He gain divine powers, or what? And, again, in which way is possible make resonating the Heart in the "bad" way?
I never made this, prefering the usual way, but im interested to this part of the game, and maybe i will try one time or another.
