Ok this is a combat storytelling question:
Say a monster has an AC of 15. Player character rolls to hit it with a melee attack.
1d20 + X... player gets a 14.
When I tell the player what happened, do I say the monster got hit but it didn't do any damage because it bounced off his armor (because maybe this monster wears armor)? Like do any of you guys use a general rule to judge what happens on hits and misses? Like an arrow to a dragon on a critical hit might hit the eye or something. Criticals are easier this way but I'd love to see some notion of what happens depending on how much they missed or hit by. Like maybe if the player misses by 5 or more, this means he completely missed etc...
