Armour Class in 5th Edition

[Mr_Tangent |\]

First time DM here, have been struggling to find out how AC works. In the first adventure we used it as a secondary health, though I'm fairly sure that's not right. So could someone explain please?

Armor class is the number you must roll on the 20 sided die (plus modifiers) to hit the target.

Thanks for that, I was using Dex to check hits. 😃

When you make an attack, your attack roll determines
whether the attack hits or misses. To make an attack roll,
roll a d20 and add the appropriate modifiers. If the total
of the roll plus modifiers equals or exceeds the target’s
Armor Class (AC), the attack hits. The AC of a character
is determined at character creation, whereas the AC of a
monster is in its stat block.

*snip*

Rolling 1 or 20
Sometimes fate blesses or curses a combatant, causing
the novice to hit and the veteran to miss.
If the d20 roll for an attack is a 20, the attack
hits regardless of any modifiers or the target’s AC.
This is called a critical hit, which is explained later
in this chapter.
If the d20 roll for an attack is a 1, the attack misses
regardless of any modifiers or the target’s AC.

This reminds me of when I started playing AD&D in primary school in '82.

My DM asked me to roll '3d6 in order six times and tally the results' for my stats.

I proceeded to roll [3d6]*6 for each ability score. Those were some good stats.

the good old days, it wasn't cheating if you didn't know any better
