Grand Advent (神煌臨, Shinkōrin), introduced in BS46, is a subcategory of Advent, which allows the player to advent by moving a core from a Grandwalker Nexus to a spirit as the cost instead of sending the Soul Core to trash. The text reads as follows:
- Flash - Grand Advent: [Condition] (Timing) By either sending your to the Trash, or putting a core from your Grandwalker Nexus to a spirit you control, stack this from your hand onto your target spirit.
Only Avatars of Supreme Deities (and their respective Song Princess versions) have this effect, limiting it to few Spirits and decks.
Grand Advent allows the player to Advent a strong Spirit while still keeping the Soul Core stored, allowing for multiple Advents or Adventing and still have Soul Core-locked effects available and it also doubles as a discreet Release effect.
