I've been playing and/or GMing EotE since release, and as I was reading through some other threads today I realized I'm still hazy on when to use Vigilance vs Perception. So is it that if you're actively looking for danger (or something else) you roll perception. If you are not expecting trouble, and thus not looking you roll vigilance?
example 1: You are sneaking through a pirate infested forest, trying to get to their hidden base. You're on constant lookout. A band of brigands is hidden ahead, Roll Perception.
example 2: You are grocery shopping, pondering whether to get the regular of extra bloody Meaty Puff's cereal. A band of bounty hunters is hiding behind the dairy counter ready to unleash buttery blastery death upon you. Not expecting anything do you roll vigilance to notice them?
I've pretty much just used vigilance for initiative, and the occasional "did I bring this with me roll." Am I doing this wrong?
Thanks all.
