Argonians were pretty badly outclassed in Requiem, even with BtC, so I made a quick little patch that merges changes to the Argonian race, adding Requiem keywords to the racial records of Argonian Upgrades, and changing values to match BtC. Where things conflict, BtC wins out.

Requires Requiem and the original Argonian Upgrades by WinsomeMinotaur. Does not technically require BtC, but uses BtC's passive version of histskin and BtC's values where they differ from those of Requiem.

Load this patch after both Argonian Upgrades and BtC. It should not matter where Argonian Upgrades is relative to BtC or Requiem.

Will be incompatible with anything that alters Argonians' racial record, even a little bit. The changes to Argonian vampires (vampires are a separate race, it's dumb) will also be incompatible with some things that change vampires, if they do so by changing vampire racial records. However, these should all be simple overwrite incompatibilities, so nothing that will break your game; you'll just only get one version of Argonians, this mod's or that of whatever is overwriting it. If you want this mod to beat up whatever it is currently beating it up, load it after that thing.

Let me know how this works! I've yet to do an Argonian playthrough with this myself, so it's possible something isn't working.

Thanks to Fagdor for reminding me to add the Argonian Upgrades venom spell to the Serpent Stone list.
