Hiya mate! 
Its an interesting question and one with no easy answer.
If Thor (in possession of 4 artifacts) slays Odin (who also has four artifacts), can Thor not just lift Odin's artifacts and use them? Or can he use 2 of Odins artifacts and 2 of his own?
My take on it is this:
Using someone else's artifacts is limited by your portfolios and/or alignment, because artifacts are an extension of the deity.
These need to be compatible otherwise in your hands the artifact will
A) allow you to wield it but only at your power level.
B) allow you to wield it but only act as a non-epic item.
C) not allow you to wield it.
D) not allow you to wield it and injure you if you try to do so.
So you can see how the deviations are set up.
Possible 2 portfolios, possible 2 alignments.
Incidently, mortals get by the lack of portfolios by using the artifact for a special purpose.
So say a Priest of Orcus is lent the Wand of Orcus. While in his possession its treated as a non-epic item (drop two steps to B since the priest has no portfolios). But if the Priets uses the artifact for the specific purpose of advancing the gods portfolios he could gain its full power for a limited space of time.
Does that make sense, what do you all think of that mechanic?

Just a quick question. (It may have been answered much earlier, but I dont remember seeing it) An Immortal is limited to 4 artifacts at once (possibly more, but with downgraded powerlevels) does this mean the Immortal can have/wield/use 4 artifacts or that he or she can create 4? Is there anything preventing a deity from having 5+ artifacts at once (possibly creating some/all of them himself) but leaving some 'at home' or simply keeping them on his person but not used? (Like keeping a magic sword at your side, or having a ring of total-damage-reflection in your pocket while your wear your four rings of Omni-death)
