Im curious what does these weapon damage descriptions mean?
4d6

1d6

Edit:
I found it:

• The first number is the amount of dice.

• The letter 'd' is short for 'die' (as in a die roll)

• The second number is how many numbers are in that die. 

So 1d6 is one regular six sided dice roll

4d6 is you roll 4 six sided dice and roll them, add up the numbers you rolled and that will be your damage.

Exactly! The game uses this dice notation. If you see something like 2d8+2, that means you will deal 4 to 18 damage per roll/attack. Next update will add some descriptions and will show more info about hit probability and attacks.
