Amulet of Egorim

Forged by the archmage Egorim, this amulet had the power of all schools of magic. However, after the mage's demise, the amulet became corrupted and is now only necrotic. Not only was the item regarded as cursed, but it is also believed that the amulet may be the phylactery of the evil mage himself, securing his fate in the eternity of lichdom.

If a non-necromancer attempts to wear this necklace the user must succeed on a DC 20 Wisdom Saving Throw or have the Curse of Egorim. Only a Greater Restoration spell with a DC of 18 can break the curse, attempting to destroy the amulet in any way causes the wearer to suffer 3d12 necrotic damage even if removed. For every hour the amulet is 15 ft. or more away from the cursed, the wearer suffers 2d12 necrotic damage.

While cursed, the following occurs within the timeframe below. The user must succeed on a DC 20 Wisdom Saving Throw every dawn. If a Wisdom Save succeeds, they must reroll that same Wisdom Save on the next day. If fail, they suffer the effects and must go to next effect on the next dawn.

Immediately - The user suffers a horrible headache and suffers 1d12 necrotic damage. Egorim contacts the individual to reunite the amulet to him.

3 days - The user suffers 1d12 necrotic damage and has disadvantage on all Wisdom Saving Throws. Egorim tells the user they have one week to find him and that the amulet has powers if attuned.

7 days - The user suffers 1d12 necrotic damage and receives 2d6 radiant damage for every hour in direct sunlight. All attacks against them have advantage.

8 days - The user's skin begins to peel and die. They suffer 1d12 necrotic damage and receive 3d6 radiant damage for every hour in direct sunlight.

9 days - The user gets disadvantage on all attacks. All magic attacks deal half damage.

10 days - The user becomes a thrall of Egorim and must obey his will. Only a Greater Restoration Spell can return them back to their original form. If the amulet is dispelled or destroyed, the user dies.
