Forum:Dark Room of Nightmare Help

If I had a Dark Room of Nightmare (DRoN) on the field and Skull invitation active, or any card that inflicts damage whenever a card is sent to the graveyard(e.g. Coffin Seller, Fatal Abacus), does the room chain onto EACH card? OR does it add onto the total as a lump sum.

For example: If I used a dark hole and my opponent had two monsters. Would nightmare room add an extra 300 for each monster? Or would it end up chaining after both monsters are destroyed.

Would it be 300 from [Skull invitation] + 300 from [DRoN] + [Skull invitation] + [DRoN] totaling for 1200.

Or would it be a 600 total from the two monsters for [skull invitation], and another 300 from [DRoN] totaling for 900.

Also, would the same apply if my opponent sacrificed monsters? Or if spells and traps are activated in a chain?

For instance, if they synchro summoned, would the same effect above apply? Or if my opponent and I were chaining magic and traps onto each other.

Also, if I were to activate chain strike, would DRoN chain with Skull Invitation and Chain Strike separately? Or would it chain onto the end of both effects.

So in other words... Would it be [Skull Invitation] + [DRoN] + [Chain Strike] + [DRoN] totaling for 2100 points

Or would it be... [Skull Invitation] + [Chain Strike] + [DRoN] for a total of 1400 points
