i was just wondering what determines if you hit or not. for the life of me i can not hit people. my odds are always low and i was wondering what im doing wrong. ive made it to lvl 4 and im still having trouble understanding the whole ac and hit rate, ive never played dnd i would appreciate any help
Short version...
Every time you try to hit, you will roll a 20 sided die, add your modifiers, and try to get a number greater than your targets AC.
The typical modifiers you will add are:
Your relevant ability modifier
Your proficiency bonus (always +2 until level 5)
Relevant ability modifiers are:
Strength for most melee attacks
Dexterity for ranged attacks or finesse melee weapons
INT for wizard spells, cha for warlock, wis for cleric
So first thing you want to do, is make sure you are attacking in a way that uses your best ability. If you are a strength fighter using a bow, you will do poorly.
Second, there are several situations that will modify your chance to hit further.
If you are flanking an enemy in melee with a friend, you will roll with advantage, meaning you roll two dice and take the best result.
If you are threatened by an enemy in melee and you try to do a ranged attack, you will roll with disadvantage, meaning you roll two dice and take the worst result.
A prone enemy gives melee attackers advantage but ranged attackers disadvantage.
Also, cover and concealment will make ranged attacks less successful.
I’m sure there more but that’s a decent primer.
