Rulings
- If you have a Soul-Absorbing Bone Tower equipped with Raregold Armor and a Zombie-Type monster, your opponent cannot attack. Even if you have a Zombie-Type monster, Gemini Elf, and a Soul-Absorbing Bone Tower equipped with Raregold Armor, your opponent cannot attack.
- If you have another Zombie-Type monster and Soul-Absorbing Bone Tower, your opponent cannot attack the Soul-Absorbing Bone Tower, but if you equip the Soul-Absorbing Bone Tower with Ring of Magnetism your opponent can declare an attack but must attack the Soul-Absorbing Bone Tower equipped with the Ring of Magnetism.
- If you have multiple Soul-Absorbing Bone Towers and no other monsters, your opponent cannot attack.
- When your opponent attacks your Soul-Absorbing Bone Tower and during the Battle Step you activate Call of the Haunted to Special Summon another Zombie-Type monster, then a replay occurs (and you send 2 cards from your opponent's Deck to the GY).
- If DNA Surgery is in play changing all monsters to Zombie-Types, and a monster that was not originally a Zombie-Type is Special Summoned, Soul-Absorbing Bone Tower's effect is applied and you send 2 cards from your opponent's Deck to the GY.
- If a Zombie-Type monster is Special Summoned on your opponent's side of the field, Soul-Absorbing Bone Tower's effect activates.
- If a Zombie-Type monster is Special Summoned face-down (with The Shallow Grave, etc.) then Soul-Absorbing Bone Tower's effect does not activate.
- If multiple Zombie-Type monsters are Special Summoned simultaneously, Soul-Absorbing Bone Tower's effect is only applied once (so send just 2 cards).
- If Soul-Absorbing Bone Tower is Special Summoned by itself, its effect is not applied for its own Special Summon.
