Revamp legendary weapon concept!
So this is my Idea:
It all starts off with the personal story. (cutscene) Some time during the storyline your character finds this warped piece metal on the ground. When your character picks it up and stares at it visions begin to flood their mind. These visions show a decimated world. All that stands is a massive dragon and the silhouette of a soldier challenging the dragon. The vision changes into their battle which was waged on mountains and in the sky both seemingly inexhaustible in power. Then your character sees the dragon slain and falling from the sky as the soldier watches, nearly defeated and bleeding out. A moment of silence before the dragon whispers a final word and explodes. The soldier is consumed in light and your character snaps back to reality. You then obtain a [Mysterious Metal] which will be the base of your Legendary weapon/armor/trinket. This is not tradeable.
Later on, your character finds a peculiar anvil asside a very weird forge and a hammer. This place becomes a Pact base and the anvil and forge provide the interface for upgrading your Legendary. This lets you customize the name, stats, looks, special effects, F button attacks and attack/armor effects (compared to sigils). This anvil can also allow you to reset your Legendary by removing every item you’ve put towards your Legendary. Doing so however will not give you all of your materials back. There upgrade limit is high to the amount of stats and effects you may place on these BUT the mat costs increase the more you upgrade.
Upgrade materials for these weapons are found as guaranteed drops in events although this type of drop only occurs once per day per event. These mats are also SBoA.
If done properly, it would turn combat from this into something close to this. Players will get rewarded every step in their Legendary’s development. Those who are persistent will get farther. People have another way to show off their kitten.
