I'm not sure if this is in the 1.19 as well, but I would expect so.
Reflection also reflect heals directed at the shiel-bearer, right?
I just had a game where the lv.3 ai tried to heal itself and failed due to a reflective shield. The ai was in dire need of hp (it died the next turn), but I assume that it wasn't desperate but just unable to understand the way it's shield works.
