If you are asking about "Reflects 15% of the physical damage taken from basic attacks and on-hit effects back to its source as magic damage", then the damage reflected is based on damage basic attacks and on-hit effects + abilities before any resistances. However, the damage reflected is magic damage, not true damage, so the damage reflected can be countered by magic resistance.
