Which combined artifact is the best?

Alliance of Angels, a great item, takes a long time to acquire (but it's worth it). Cloak of the Unholy King, a dream for any Necromancer Hero. Cursed Armor is decent. Titan's Thunder, suitable for some, if you have a super powerful mage, this item will only be useful if they are out of mana; otherwise, it's helpful. Elixir of Life, a necessary item for a large army. Sniper's Bow, no penalty when firing, a very good item for an army that includes archers.
