A Ventricular Lance is an item which gives an +1 armor piercing to all of an agent's attacks for one turn. It is active during the enemy's turn as well (for example during ambush or overwatch attack). 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.
