Final Fantasy XIV Patch 6.4 introduced another Extreme Trial, this in the form of The Voidcast Dias.
If players are not at the required level to complete The Voidcast Dias and unlock the Extreme Trial in FFXIV, they can either purchase weapons and armor from the market board or run The Aetherfront.
However, before you can jump into The Voidcast Dias Extreme you will need to be item level 630.
After that, you can unlock The Voidcast Dias Extreme in FFXIV.
