Robust Offering

Robust Offering is a Season of the Witch material with a stack limit of 99. Depositing one in an Altar of Summoning starts a Robust (Tier 2) encounter, and the receptacle is marked by a hologram of two crossed Hive swords.

Robust Offerings can drop from activities. After unlocking the Opaque Card at the Lectern of Divination, the Offering Shrine vendor in the Altars of Summoning sells them for 2,500 Glimmer or 5 Feeble Offerings. The Lectern also grants 5 once the card is collected, and four can be traded to the vendor for a Powerful Offering.
