The Tradecraft Skill in GODLIKE (and Maybe Delta Green)

My home (well, Discord) group is playtesting the first scenario of Operation TORCH, a looooooong-gestating GODLIKE campaign about the Allied invasion of North Africa in 1942. The opening scenario features American Talents recruited by the OSS's Secret Intelligence division to search for enemy Talents in Casablanca. An integral element is the new Brains skill Tradecraft. Playtest it and let us know what you think.

(As an aside, I'm considering a version of this to replace the Disguise skill in Delta Green. We decided against Tradecraft as its own skill early on as too duplicative of existing skills like Persuade and Stealth, but developing the Tradecraft skill with Allan Goodall for GODLIKE makes me reconsider. Thoughts?)

BRAINS SKILLS

Tradecraft: Avoiding attention and suspicion while gathering and sharing information. Spying in plain sight. 

USING TRADECRAFT

Tradecraft identifies and mitigates the risks that others might recognize spying when they see it. Tradecraft is to spying what the Tactics skill is to combat operations. It covers communications, behavior, cover identities, and setting up safe houses, radio posts, or bases of operations. Where Stealth avoids being seen, Tradecraft avoids drawing attention and suspicion during observation. Spies sometimes work against each other with opposed Tradecraft rolls.

Tradecraft is often used in conjunction with other skills. Dropping a coded message where another agent can pick it up is Tradecraft, but coding the message in the first place is Cryptography. Placing an electronic listening device in a room requires Tradecraft, but constructing the device requires Electronics. Searching a room for a hidden letter uses Tradecraft, but sneaking into the room in the first place requires Stealth. Knowing when and how to send a radio transmission without it being heard by the enemy requires Tradecraft, but making it comprehensible requires Radio Operator. Remember that calling for two rolls doubles the chance of failure. When two skills are necessary to a single action, use the smaller of the two dice pools and look for a single success.

TRADECRAFT SKILL FUNCTIONS
