Sure.
I started as Genin and I was promoted during Night 1.
Day actions: I used my Gates line. The day before, I used a defensive gate that would let me heal wounds if I took any during the day phase.
Night actions: last night I used my Taijutsu support ability to grant an extra action to a teammate, per a direct request in PM. I did not receive any feedback about being injured, blocked, or disabled.
If you want me to include targets, tell me if you want that now or after the night resolves.
