That part of the tooltip was actually leftover from its previous mechanics, which was a heal-over-time that blocked basic attacks, while preventing Aldric from using basic attacks. So by being able to end the effect early, he could use basic attacks again. Regardless, I'm making changes to the ability again, so the info is no longer relevant.
