I'm creating a nagaji oracle, and stumbled upon the Cold-Blooded Oracle Curse from the Monster Codex. It reads:
Your blood turns sluggish without sufficient heat, and you must seek warmth and shelter earlier than most. This oracle curse is common among lizardfolk and other oracles with the reptilian subtype. You take a –4 penalty on saves against cold spells and effects, and whenever you fail such a saving throw, you are staggered for 1 round. You can survive without food four times longer than a typical creature of your species before you begin to starve.
Initially I was going to take Clouded Vision as my curse, but this one seems much better. The only downside that I'm really seeing is "a –4 penalty on saves against cold spells and effects." However, the first sentence has me a little tripped up. I'm not sure whether that is supposed to add flavor, or whether there is a set of game mechanics that actually determine how fast I would need to "seek warmth and shelter."
Is there a way to operationalize the first sentence, or is that just flavor given to the curse? If there are rules governing the first sentence, how do I apply them in PFS scenarios that generally have shorter in-game time frames?
