How this would work is that one of each daedric artifact exists in the world for one player to equip. They could drop from anything and everything but have an extremely low drop chance. Once a player picks it up they can wield it for 1 hour before it disappears again for a new player to find. So 15 daedric artifacts would exist for 15 players to wield. With an extremely low drop chance some artifacts may only ever been seen once or twice in months of looting but should the stars align all 15 could be out at once.

I would also disable achievements and leader board status for people running dungeons with artifacts. Simply because it would give them an unfair advantage. The only purpose to doing it with an artifact would be to maybe get some cool new gear you were grinding for or some nice extra xp to help with that cp grind.

With the sole purpose of having fun and making people happy I think it would be a fun mechanic but this is just a fun theory for ideas on how it might work!

Each artifact will do something insane to help the player! I will list some of my ideas. Post your own as well.

Hermaous Mora and the Ohgma Infinium- Max out all crafting skill lines and fill with with skill points. Then give the player knowledge of every motif. Then for 1 hour they can craft anything! Of course they would still needs the mats but they can have fun with it.

Peryite and Spell Breaker- Reflect all spells at the attacker (Including Bosses). Of course they would still need to block draining stamina but could be very dangerous non the less!

Mehrunes Dagon and Mehrunes Razor- A dagger with the chance to one shot anything!

Malacath and Volendrung- Every heavy attack with this two handed hammer restores all your stamina and increases the damage of your two handed abilities significantly.
