Thermal Detonators are very powerful explosives. It's what they use for the Deadman's Switch illicit upgrade card.They brought Thermal detonators for space combat?
Thats like tossing hand granates at planes - like in the very early phase of WW1 air combat.
Until the Fokkers came with machine guns ... yes that was kinda unfair and cheating.
It should be less powerful then a seismic.
And thinking about the fragmentation of a hand grenade (which a thermal detonator literally is) and the effects of shrapnel in X-Wing (Flechette Weapons) I came to the conclusion that
this is the Stress-only bomb to complete the set of bombs: hit, crit, ion, stress.
Cost: 1 or 2 points.
Maybe the girl in the mandalorian armor provides unlimited ammo for thermal detonators.
I don't know if this would fit her character, since I haven't watched the SW Rebels series.
But I promise to watch the SW Imperials series.
