Effect
You can Special Summon this card (from your hand) by banishing 1 LIGHT Dragon-Type monster and 1 Dragon-Type Normal Monster from your Graveyard. If this face-up card on the field would be destroyed, you can Tribute 1 face-up "Hieratic" monster instead, except this card.
The monster effect "You can Special Summon this card (from your hand) by banishing 1 Dragon-Type LIGHT monster and 1 Dragon-Type Normal Monster from your Graveyard" is an effect that is not classified as an Ignition Effect, Trigger Effect, Quick Effect, or Continuous Effect.
A Chain Link is not created when Special Summoning "Hieratic Dragon of Su" with its own monster effect.
When Special Summoning "Hieratic Dragon of Su" with its own monster effect, as a procedure, you banish 1 Dragon-Type LIGHT monster from your Graveyard and 1 Dragon-Type Normal Monster from your Graveyard, and then perform the Special Summon. (This is not treated as the process being completed upon banishing.)
The monster effect "If this face-up card on the field would be destroyed, you can Tribute 1 other face-up 'Hieratic' monster you control instead" is a Continuous Effect. (This can also be applied during the Damage Step.)
