You may have heard of Requiem, but have you heard of Ad Vitam?
Ad Vitam is an add-on that adds several useful features to Requiem. The two most relevant are the new remnant type: the Wraith, and the ability to create a corpse from the ground.
Alongside these are a few world-gen mods. For the overworld, we have Tectonic and Towns and Towers for a fresh exploration experience when you're flying around as an incorporeal being! The Nether and End have been completely overhauled with Incendium and Nullscape.
And of course, the modpack includes optimization with Sodium to ensure your game runs smoothly.
