Nightblood doubt...?

[Xabben]

[WARNING, SPOILERS OF RoW]

At the end of RoW, Taravangian uses Nightblood to kill Odium. However, there is something a little bit strange in how Nightblood appears in Odium's vision. Some people say that Nightblood can appear in the vision due to the high amount of Investidure it contains. However, in that particular moment, the sword was inside its aluminum sheath, which should have "blocked" the effect of the Investidure. Am I missing something?

[Frustration]

It's not investiture. Odium's vision distorts the realms there. Taravangian's body is still in the physical realm, and he could grab Nightblood. Once Nightblood was in his hands Taravangian could bring Nightblood into the visions.
