I noticed in the converted animals thread that a couple snakes have an Accelerated Strike power, apparently distinct from Predator Burst, giving them a bonus to "burst speed" and strike. Should these be taken as constant, passive bonuses, or as something akin to a Predator Burst that only applies to the first round or so of combat? Granted, I suspect it's ultimately up to the GM, but I'm curious if there's any kind of consensus or a rule somewhere I'm missing.
