Iron Maiden

Custom Kidou

• Name: Iron Maiden
  
• Type: Offensive (mix of hado #90 & 91/bakudo 92)
  
• Number: Daisuke Exclusive
  
• Effects: Upon saying the incantation, lengths of gold spiritual fabric wraps around the victim's body, completely mummifying them. The victim then becomes encased in a very snug sarcophagus shaped container made of what seems to be ebony. The instant it shuts the target in, the inside becomes much like a vacuum, slowly suffocating the target. The sarcophagus then begins heating to dangerous levels, burning the victim inside it severely. With but a motion of a hand, a dozen spears of electrified energy manifest, surrounding the sarcophagus and running it through from head to toe in an instant.

• Notes:
  

Daisuke can only use this once per 24 hours. This attack may be used more than that but it has adverse effects on those that do so and don't have the spirit energy to back it up. It takes 30 seconds for the spirit fabric to mummify the victim, the sarcophagus shutting around him/her immediately after (one post). Once fully encased and mummified, the sarcophagus then begins heating up at an accelerated rate while the user begins charging/manifesting the energy spears (one post). Upon complete manifestation, the target is then hit with the spears. Upon being struck, the sarcophagus remains substantial for approximately 30 seconds before disappearing.

Total time needed: 3 posts

The incantation is required.
Two lines, loosely based off of a mythological creature.
Please discern the time (in posts, or seconds)it takes for the sarcophagus to fully encase the enemy. As well as when the sarcophagus begins to heat, and how long it takes for the electric spears to generate.
