Janx said:at 15th level, a fighter has 10+5.5*14 hit points (statistical average, no con bonus). That's 87 hit points. A heavy crossbow does 1d10 damage, double for crits. Max damage then is 20 damage. That's a drop in the bucket.
Ah, you neglected the Fortitude save (DC 10 + damage dealt) or die. Since the coup de grace is an automatic hit, and since saves are failed on a natural 1, a dozen crossbowmen would have a 1 - (0.95)^12 = 46% (approx) chance of killing anything that is not simply immune to the damage. If the coup de grace is allowed.
That's quite a threat, IMO. (In the one-on-one situation, it's a lot less terrifying, but still a non-trivial risk to the character. A 5% chance of outright death is something I don't think most players will simply laugh at... most of them have seen too many natural 1's at just the wrong moment to be unmoved.)
