Disclaimer beforehand- This does not involve any Buying of Warhorns of Utumno or Outside regions outside of Utumno. This is talking of Using Invasion Mechanics to make Utumno more difficult.
So I was wandering around the wiki and saw that Utumno has the ability to invade areas. I thought of it for a bit and I thought that these Utumno invasions could be used to make Utumno a little bit more difficult. They could be used for more immersive or PVP actions in Utumno.
The First variety of the "invasion" would be most common in the ice level of Utumno. This would contain 4-5 waves of orcs, arches, and frost wargs. This would be a meager show of power from the Legions of Morgoth. This would be uncommon at the Obsidian level but becomes more common as time goes by. A possible achievement would be "A Meager Show of Morgoth".
The Second would be a more powerful variant of its first sibling. This would be the dominant variant of the Obsidian level which contains 3-4 Waves but will contain small trolls along with 3-5 Tormented Elves and 8-10 Orcs. This variant will be virtually non-existent in The Fire Level. A possible achievement would be "A Knife From Udun".
The Last and Third Variant is the most powerful variant of its family. This however would only contain 1-2 Waves. This would have 2 Balrogs, up to 3-4 Giant Trolls and 10-20 orcs, and 5-9 Tormented Elves along with a couple of wargs. This would be practically non-existent until you awake the Melkor Plate. This would happen at the end of The Melkor Plate Activation. A possible achievement could be "The Final Show of Morgoth" or "The Mace of Morgoth Broken".
A possible title for Defeating the Third Variant- "The Bringer of Justice" or if you defeat all of them and escape from Utumno you could receive the title "The Avenger of Beleriand"
Tell me what you think! I would love to see some feedback. I make my future suggestions better from feedback.
Edit- Changed The Will of the Valar to The Bringer of Justice
