Do you have any other suggestions for the mod?
make the Necromancer's Amulet and the Mana Absorption Pendant major artifacts instead of relics, and the Enlightened Chainmail the opposite – a relic. Also, the Necklace of Victory could have a bonus of +2 to luck and be made a relic; I think that's a good idea.
Justification: The Necromancer's Amulet is only suitable for one faction and doesn't provide that much benefit. Therefore, if this relic spawns for a faction other than Necropolis, it's only worth 3500 gold. The Mana Absorption Pendant is also situational, so I think it could be made a major artifact. The Enlightened Chainmail provides twice the bonus of the Turban and is also a major artifact, which is unfair. I suggested the Necklace of Victory to add a relic among the necklaces because only the Pendant of Skill will remain if the first two necklaces mentioned are removed from the relics.
