Oh, I've been meaning to watch that video. Going through it now and I'd guess that Embrace is being macroed with Adlo and Physick. Virus is likely a focus target macro with a party tell. E4E might be combined with a party tell as well.
Edit: No clue what those numbered macros are doing.
Anyway, I have a setup similar to her's except I don't palette swap since I have enough buttons using the newer trigger button hotbars. Adlo/Physick + Embrace macro
Code
/pac "Embrace" <t>
/ac "Physick" <t>
works well for most fights even though it leads to a lot of fairy overheals, but it's better than her just sitting there waiting for the target to cross the heal threshold. Requires that Eos be on Obey but she should always be set to that anyway. You can just swap those out for the regular spell when you need to micromanage Embrace (Leviathan EX, for instance).
Only other macro I have that I can remember is
Code
/ac "Swiftcast" <me>
/ac "Resurrection" <t>
Hit it once for normal Swiftcast, tap it twice while targeting a dead person for SC Raise. Oh, and the Virus one.
