Seat of Sacrifice

[hagare]

Playing on PS4, I can't keyboard smash (it goes into the text box) but I find that two buttons pressed alternately is enough. The D-pad can be used as well as the symbol buttons, though I prefer to shift grip on the controller so I can hit the Triangle and Circle buttons with my pointer fingers instead of my thumbs.

you can still use the shoulder button can't you.
that's 6 buttons you can smash. 4 shoulders and 2 face with thumbs
