Broodlord more logical mechanics of attack

broodlord firing acid spores like the guardian, broodling only spawns if the target dies in the purest old queen style

Queens can launch a small spore cluster to a target non-robotic ground unit. The spores then attempt to fertilize within any organic matter in the target, even making their way through armored shells to reach their organic destination. The spores metabolize the victim immediately and within a few seconds, the spores gestate and produce a pair of Broodlings which, upon an explosive birth, destroy the host.
