Fail-Safe Detonator

Use in any phase when a BATTLESUIT model
from your army is destroyed. Before removing
it from play, instead of triggering any other
abilities that trigger on death, roll one D6 for
each unit within 3" of that model, adding 1 if
the destroyed model had 12 or more wounds.
On a 3-5, that unit takes D3 mortals; on a 6+,
that unit takes 3 mortals.
