A Ventricular Lance is an item which gives an +1 armor piercing to all of an agent's attacks for one turn. Ventricular Lances can be bought from some Nanofabricators for 700 credits, or sometimes from Monst3r for 560 credits; additionally, Archive Shalem 11 starts with one.
An agent can use a Ventricular Lance on another agent, a rescued Courier or Prisoner, or a hacked drone. In this case, the target of the Ventricular Lance must be on a tile adjacent to the agent using it. To use a Ventricular Lance this way, select it in the agent's inventory, and then click on the Ventricular Lance icon attached to the target unit.
