Wondrous Item, Rare (Requires Attunement)
A pendant of pressed gravebloom, blessed in a night-long Sporesung rite so that it steadies the self against the Deep's slow theft. This is an attuned magic item, not a bonded symbiote: it occupies one of your three attunement slots and never a bond slot, and wearing it carries no risk of Infestation (see Chapter 5).
Steadied Self. You have Advantage on Communion saving throws.
Quiet the Bloom. Once per Long Rest, you can spend ten minutes in silent communion with the amulet to reduce your Infestation by 1. This has no effect if your Infestation is at Step 5 or higher.
