It would be nice if NPCs wouldn't get angry when you use Bladesong Climax in a public place.
"Unleash the full damaging and healing effects of your Bladesong at once. Your Bladesong Damage Charges will harm enemies an additional 1d6 Force Damage, and your Bladesong Healing Charges will heal you and your allies an additional 1d6hit points."
Apparently the Force Damage gets dealt even when there are on enemies around, and NPCs don't like it when you are aggresive or something.
So far I've only used this after a fight, not in the middle of a fight. Maybe I should just wait until the Damage Charges have dropped to zero before triggering the Healing Charges.
