During CT's last boss to keep the Egi alive for flares, "Place" it on the platform then "Steady." There's no default to Obey but just start fights in "Steady" and use Obey to pinpoint specific targets, like for example, Plumes in Garuda so Garuda does some damage while I prep her AoE (Not Enkindle)

Once you get the hang of it it becomes second nature
