Bribery

Bribery pays one of the enemy's own agents to work for you. From then on, every covert operation YOU run against that realm is twice as likely to land. It does nothing to the operations they run against you.

The agent stays on your payroll for the rest of the game, and you can only hold one inside a realm — the menu refuses a second attempt, at no cost. It is also what Expose Enemy Ops needs before it can shield you from that realm. Since the bribe itself is only carried out at daily maintenance, the earliest you can expose that realm is the day after you pay for the bribe.

Bribery is the hardest operation on the menu to land, so expect to pay for several attempts.
