Not Enough Love

[Lelouche Vi Britannia]

Okay guys I need some help. I'm working on a quest currently and what seems to be happening is that Neyru's love is it's not preventing the knock-back caused by damage combos, just the damage. That's probably what is supposed to happen, but I need it to not do that.

Is there a way I can get the spell to not simply ignore damage, but pass on actual invulnerability like the stopwatch does?
