If you deploy you Speculo just outside the enimy deployment zone can you put the mine in the deployment zone?
Could you deploy outside the deployment zone -AND- make a WIP roll to deploy inside? Allowing you to extend your deployment area and place the mine in the DZ as it is now part of your available deployment area?
I very much doubt it. During the Deployment Phase, allows the user to deploy anywhere on the game table except for the enemy Deployment Zone. ... Allows the user to deploy inside the enemy Deployment Zone by making a WIP Roll. The WIP Roll is tied to actually deploying inside the enemy DZ.
You need to deploy the speculo in the Enemy's DZ to be able to roll WIP and, if succesful, deploy there (at which point you can deploy the mine there too).
Note that the sequence will be: Place the Speculo and the Mine, If this is in the enemy DZ, roll against WIP, If you fail, Disperse and lose both the deployed Mine and IMP state, potentially ending up back in your own DZ touching the table edge.
