Humility...may be difficult for Tane. He's not going to land a damn hit and M'baka's going to beat the shit out of him, but he can laugh off damn near anything short of murdering his friends in front of him for no readily apparent reason or randomly beating him up in the middle of the night. He Whose Laugh Is Thunder doesn't just mean he laughs really loud, it's just that whenever lightning strikes/calamity hits, his laughter's not far behind.
