How to Level Up
Levelling up may seem like a daunting process, but it breaks down into a few simple steps.
1. Gain more hit dice
The amount of hit dice (d8, d10, etc.) should equal your level. If you’re level 2, you should have 2 hit dice.
2. Add more hit points.
Each time you gain a level, you gain 1 additional Hit Die. Roll that Hit Die, add your Constitution modifier to the roll, and add the total to your hit point maximum. Alternatively, you can use the fixed value shown in your class entry, which is the average result of the die roll (rounded up).
For example, a fighter currently has 12 hit points and levels up from 1 to 2. She gains an additional d10 hit dice. Her new hp total is 12 + (5+1) + constitution modifier.
3. Check class levels table then add new features
For example, wizards get more spells and a fighter can hit things harder
Ability Score Increase and Feats
At certain levels (4, 8, 12, etc.) your character will gain an ability score increase which will allow you to increase one ability score by two or two ability scores by one. Alternatively, you can forgo this increase and instead gain a feat. Feats are powerful and very specialized features that give you bonuses to things that you want your character to be good at. For example, Alert gives your character a +5 to initiative along with some other bonuses.
