• "Solemn Warning" can be activated during the Damage Step. It can be activated to negate the activation of "Tragoedia's effect to special summon itself".

• When you activate a Spell or Trap Card that targets, you choose the target(s) when you activate the card, before your opponent decides whether or not to Chain to it. So if you want to negate the activation of a card like "Monster Reborn" or "Call of the Haunted" with "Solemn Warning", you must chain "Solemn Warning" after "Monster Reborn"/"Call of the Haunted" have declared a monster in the graveyard as a target.

• Gorz the Emissary of Darkness: Both "Solemn Warning" and "Solemn Judgment" are Counter Trap Cards so they can be activated in the Damage Step. "Solemn Warning" can be activated to negate the Special Summon of "Gorz the Emissary of Darkness". "Solemn Judgment" cannot be activated to negate the Special Summon of "Gorz the Emissary of Darkness".
  • "Solemn Judgment" cannot negate monster effects. "Gorz the Emissary of Darkness" is being Special Summoned by a monster effect. "Solemn Warning" does not have such a restriction as its effect includes the ability to negate monster effects as well.

• Solemn Warning can be used to negate the Pendulum Summon of 3 monsters.

• Soul Charge: If Solemn Warning is used to negate the activation of Soul Charge, a second Soul Charge may be activated the same turn.

• Grapha, Dragon Lord of Dark World: Returning one "Dark World" monster to the hand to Special Summon "Grapha, Dragon Lord of Dark World" from the Graveyard is a Summoning procedure. It is neither a cost nor part of an effect's resolution. If the Special Summon is negated by "Royal Oppression" or "Solemn Warning", then the returned "Dark World" monster remains in the hand.

• Grapha, Dragon God of Dark World: If your "Grapha, Dragon God of Dark World" is discarded by your opponent's card effect, then "Solemn Warning" or "Royal Oppression" can be Chained to the effect.
