Having trouble with spellcasting for custom class.

[MichealMNB]

I made a class called Knight's and wanted it to be a half caster like a paladin I have the spell slots just when I go to level up I have no known spell's.

You'll need to create your own spell list for the class (see from 18:50 in the video for how to do that). You'll then be able to select spells via the spell filter. This probably won't work in the character wizard if you are trying to use that for levelling up. For custom classes I recommend just using drag and drop for levelling up.
