Forum:Is this combo legal?

I have this combo if i have Summon Reactor on the field. I play alchemy cycle with machine duplication so i can get 2 more summon reactors on the field. Then i end my turn by playing Dark Room of Nightmare on the field. If my opponent summons a monster for the first time, do they lose 800 for each summon reactor on the field? Plus an extra 300? Or do they lose 1100 for each summon reactor on the field?

(800x3)+300=2700 or...

(800x3)+(300x3)=3300
