The volatile and destructive nature of the Mercy's weapon system forced Aeon scientists to create a simple, expendable delivery system. As a result, the payload is attached to what is little more than a guided missile.
Time is 1,600 build points divided by build power. Drain is mass and energy per second while it is building, so more build power finishes sooner and costs the same total, but pulls harder on the economy.
2100 damage in a single hit, and it dies delivering it. Good for removing a T3 mex or forcing an ACU to move. The catch is that it can be shut out completely: anti-air stops a Mercy dead where a bomber will usually get something through.
