rule of cool overwrites every other rule
does the player says he will kill the dragon in a really smart way, involving the environment and some item you gave him some sessions ago, showing he's paying attention to the storytelling? let that motherfucker kill the dragon
a lich is about to kill one of the pcs in a ritual to progress the plot? make it a heroic sacrifice and bring him back as an undead boss later on
