hmm... each bombard has 2.5% chance to drop a mod on death, 25% of dropped mods will be uncommon, 25% of the uncommons will be rare, 50% of all dropped mods will be fusion cores, and 2/3 of the rares will not be crimson dervish.

That means the chance to get a crimson dervish from a bombard is 0.025 * 0.25 * 0.25 * 0.5 / 3 = 0.0002604167% or 1/3840!

That's assuming all mods of each rarity have equal chance to drop. Oh well.
