At this point i am more interested in why Maya the aunt want miyuki to be the heir. Her brocon tedency is way to blatant, and miyuki herself other than magic ability seem so far from the way most of them act.
Well normally this would just damage your opponent so since Faris would be avoiding fatal damage and once people seen this you be more prudent with your att unless you want a double suicide.
feels like this world magic is really underpowered compared to other isekai fantasy setting, which kind of make sense since the civ that have the advanced magic has phase themselves out and getting to advance level of magic might even be a taboo in this world
