Forum:Spirit Reaper and Shadow Spell

Hi,

Hope somebody can help clear up this query.

I have a grapha face up in attack position and a shadow spell set on a previous turn. I attack an opponents face down defence position monster and it is Spirit Reaper. When the spirit reaper is flipped I used my Shadow Spell, and as per Spirit Reaper's effect it is destroyed.

My question is will the damage from Grapha's attack still go through? As shadow spell reduces a monsters attack it should be able to be used in the damage step, but we are confused over the timing of flips (considering monster has to be face up) and damage calculation.

Thank you guys,

Dunners
