So! Brailey has found herself facing a Goblin fighter!!
The first thing you do in combat is called "Rolling for Initiative"
This is very easy. You will roll a 20 sided die (aka a d20) and add your initiative modifier to it.
Since your initiative modifier is +2, you will type out "1d20+2" and put the [roll] brackets around it, either typing it out (don't forget the "/" slash on the second one!) or using the die icon above the reply box!
When you hit submit, a number will be displayed!
The Goblin Fighter's initiative modifier is only +1, so he will roll
1d20+1
Rolled 1d20+1 : 17 + 1, total 18
