Go to the Blacksmith and choose the transform option, and pick the base legendary weapon for the type you got from the list above.

Route 1 for your base weapon will turn into a Tier 1 Legendary

Here is the Route 1 required Mats

Aetherial Ore x1
The Murmurstone x50
Saurian Dragonscale x10 (Note this is the branch where it splits, it will say Insectoid gold wind, press L1 or R1, or the Xbox Respective to change it to Dragonscales)
Luxurian Ore x3

and there you have it, you get the Legendary Achievement and have a Legendary.

Now if you want a tiny bit more powerful of a Legendary Weapon, you can go for Tier 2

Here is the Tier 2 Required Mats

Aetherial Ore x1
The Murmurstone x50
Insectoid Gold Wing x50 (Yes choose the gold winds this time instead of the Saurian Dragonscale x10)
Adamantine Ore x10
Luxurian Ore x30
Dark Crystal x1 (Note this path is a branch path, with Blackguard's Amethyst x100 and Dark Crystal x1 press L1 or R1 until you find Dark Crystal x1)
Spectral Impute Soul x5

And there you have it, now you have a Tier 2 Legendary, but wait there's more, are you still power hungry?
Well time to go for the Tier 3

Here is the Tier 3 Required Mats

Aetherial Ore x1
The Murmurstone x50
Insectoid Gold Wing x50 (Yes choose the gold winds this time instead of the Saurian Dragonscale x10)
Adamantine Ore x10
Luxurian Ore x30
Blackguard's Amethyst x100 (Yes choose this option instead of dark crystals now)
Demonic Remains x10
Saurian Dragonjaw x20
Crystal of Light x10
Dark Crystal x10

And there you have it, you now have a Tier 3 Legendary Weapon, and are now ready for end game content.
