The Magic Spear was never originally stated to be a weapon-like Special Item - this was added by Project Aon (refer to the errata).
Based on this change then this would imply you can use it as a weapon-like Special Item (which is what I suspect you are asking) in later books up to the Grandmaster series (at which point it is not listed as a Special Item that is allowed to be carried over from previous books). You would not be able to use it as a regular run-of-the-mill Weapon (as its quite clearly stated to be a Special Item).
In terms of impact on gameplay, the Magic Spear provides no special combat bonus so the only issue with this I can see would be if you came across another Helghast (or similar enemy) that could be damaged by it in books 3-12.
Personally, I cannot see a problem with this unless someone can raise a situation in which you should be able to fight/avoid a insta-death due to having access to the Magic Spear.

Hi all, From FotW's Section 106 and beyond: http://www.projectaon.org/en/xhtml/lw/02fotw/sect106.htm can you use the Magic Spear as a regular weapon afterward (if you keep it), against regular enemies (even though it is a Special Item)?
