Dune: Imperium – Uprising

No — when you take an Agent turn you play a card to place an Agent on a matching, unoccupied space; you cannot place on a space already occupied unless a card or ability specifically allows it. (p. 9)

A Reveal turn happens when you choose Reveal instead of placing an Agent: reveal your hand, resolve Reveal effects and gain Persuasion, set your combat strength, then perform cleanup. (pp. 8, 12)

You set combat strength during the Reveal (base combat icons from cards/board plus troops/sandworms and any played Combat Intrigue cards are added); resolve Combat rewards per the Combat phase rules and apply tie-resolution and battle-icon rules for ties. (pp. 12, 14)

Spies are placed using Spy-specific Agent options (Infiltrate/Gather Intelligence) and occupy spy spaces with their own placement and recall rules; they are recalled according to the Spy placement/recall procedure described. (p. 11)

Persuasion is the currency you gain on a Reveal to purchase cards and spend on the Imperium Row or other card acquisitions; after purchases the Imperium Row is refilled per the card acquisition rules. (p. 13)

Sandworms can affect Combat rewards — certain sandworm effects double rewards for the Combat or change reward placement, and Makers’ sandworm interactions are explained in the Combat and Makers examples. (pp. 14–15)
