I got a bonus for nearly dying once. the villains were just beating our party in to the ground, when I decided my character (normally pretty reserved and probably the only sane one)had had enough and just snapped. the villains were so thrown of by this squishy human, who'd been beaten to a bloody pulp, getting up and starting to walk towards them while laughing manically, that some of them straight up ran away. I also got an intimidate bonus so large I actually managed to intimidate the enemy berserker, who was about two size categories bigger than me. he wet his pants.
a thought occurred to me. how are you going to explain kira and jess going off on their own, the cardinal rule is never split the party, and they're all genre savvy enough to know that it would just make it easier to kill them... oh, nate would know that too. I see.
I gave the monk - who was, functionally, more like a rogue - a stealth bonus because the guards he was trying to avoid didn't WANT to notice him, for a list of reasons as long as my arm that included fear of him, embarrassment over his audacity, and irritation at the same.
