BOOBY TRAP

Select one objective marker you control
that has a REDUCTUS SABOTEUR or
GENESTEALER CULTS CORE unit
within range. The next time an enemy
unit (no AIRCRAFT) ends any kind of
move within it, roll one D6: on a 2-4, that
enemy unit suffers D3 mortal wounds; on
a 5+, enemy unit suffers 3 mortal wounds.
Only select each objective marker once.
