Just to give a starting point.
NAME of the artefact.
CREATOR of the artefact.
WHO CURRENTLY HAS the artefact
CREATION STORIES will define the power of the artefact.
ARTEFACT ALIGNMENTS are always considered neutral unless its sheet declares it to have an inclination towards good/evil
COMPETING magic means the weaker magical item will break. Don't know which one? Toss a coin.
ENHANCING magic will only work if the magics are aligned in some way; same creator, same type of blood, etc
ROLEPLAY AFFECTING ITEMS only need to be outlined here. If you have magic doohickeys that stop toast burning, you don't have to post it.
ARTEFACTS CAN BE UPDATED if something happens to it or if someone blesses/curses it accordingly
