- When you Special Summon Fiend Skull Dragon with Archfiend's Roar, Archfiend's Roar's effect is not negated and Fiend Skull Dragon will be destroyed by the effect during the End Phase.
- When you remove an Archfiend from the field that was Special Summoned with Archfiend's Roar, using Interdimensional Matter Transporter, the effect is reset and it can be offered as a Tribute, and will not be destroyed during the End Phase.
- If the Archfiend monster summoned by "Archfiend’s Roar" is Set or is temporarily removed from the field, that Archfiend monster may be used as a Tribute and it will not be destroyed at the End Phase of the Turn.
