Bloodlust restrictions are just there: work with them as they are since there is no other option.
Also be aware that the restrictions work both ways - aerian will be restricted from harming you in the most obvious and potentially fatal ways, and you will be restricted from harming him likewise.
If this bothers you, a mutual challenge will remove those restrictions for you.
And of course, remember there are ways you can hurt opponents who have too much bloodlust to hit you.
I have heard complaints this way too, from sorfcerers annoyed at having their demons slain by people they cannot hurt themselges.
Bloodlust is a part of the land, and you must learn what it means like you learn the ladnd iteself.
