Remind us to never get on Olivia Munn’s bad side.

The X-Men: Apocalypse star posted an Instagram video Sunday showcasing some seriously impressive sword-fighting skills.

Munn can be seen spinning a blade back and forth like it’s nothing, while boyfriend Aaron Rodgers tries similar stunts in the background (and might need a bit more practice).

“Learned some new tricks…” she captioned the clip.

Munn plays Psylocke in Apocalypse, due out in theaters May 27, 2016.
