Only 4 files that show up for me on the Nexus are the normal game, the no-Dawnguard version, a hotfix and an outdated version.
It's not in file section but in readme section. Durr?
Also you mentioned Heavy Armory with it a few pages ago and it isn't on the list. How does that work?
It's not complete list and many mods that do technically conflict, do so by partially overwriting or getting overwritten by Requiem, with no additional ill effects. Of course some mods will break or be broken by Requiem in fatal way. That's why I asked what do you want to run with Requiem, because depending on what the mod does and how it may or may not conflict with Requiem.
Heavy Armory, for example, simply adds a lot of new weapon types with variants made of typical materials in game, so it doesn't really interact with Requiem apart from possibly leveled lists. Since I run Requiem after HA, even those are overwritten if conflicting and since Requiem applies weapon damage changes by the means of altering GMSTs and skill mechanics rather than editing individual weapons, those changes are automatically applied to HA. The only possible problems left are balance issues with some new weapons in the context of Requiem's altered combat gameplay, but even those are not as severe and kind of even out by themselves as enemies may use those weapons as well. On the upside I have shortswords, longswords, hatchets, mauls (1h warhammers since "warhammer" is already taken by Skyrim for massive 2h ones), clubs, spiked clubs, 1h short spears, 2h spears (both using sword anims because, sadly, Bethesda), quarterstaves, halberds and glaives in addition to vanilla weapon types.
I've been running older version of Duel with Requiem (in this order), and while I don't recommend it (mechanics becomes a bit clunky and may be too hardcore - think proper tactical shooter where you just die if you do anything wrong) it will work rather smoothly even though those two mods definitely do conflict.
