Panic Tests
A Panic test is simply a Psychology test -- pass it and nothing happens; fail it and the unit immediately flees (see Direction of Flight below). A unit only ever needs to take one Panic test per phase (Movement, Magic, Shooting, Close Combat), no matter how many separate reasons arise for one -- mark units that have already tested if it helps keep track in a larger game. When several of the same army's units need to test at the same moment, their controller chooses the order.
Three situations exempt even the most cowardly unit from testing at all: being in close combat (the fight itself blots out everything else); already fleeing (nothing left to accelerate); or having already passed a Panic test earlier in the same phase. Outside those exemptions, the most common triggers are covered under Causes.
