Unicornbone Necklace (unique item)

Name: Unicornbone Necklace Tier: Unique (could be legendary if it has additional negative traits) Lore: Made from the bones of the second luckiest unicorn. She lived second longest, at least. Effects: Lingering Unicorn Luck +1 multiluck -50% luck Mother's Blessing Unicorn towers receive +100% luck

Maybe this could start as an incomplete unicornbone necklace with reduced stats or increases penalties. If a unicorn dies wearing it, then it would be a completed unicornbone necklace with the bones of the last two unicorns. Maybe that's too dark...
