So I read this:
Spell save DC = 8 + your proficiency bonus + your Intelligence modifier
Spell attack modifier = your proficiency bonus + your Intelligence modifier
Now, in this case is 8 just a base number or is that supposed to be the intelligence score? I am mainly confused because if it is the score and that is for a wizard that it very low. I'm trying to determine the numbers I would then require to place for spellcasting ability, spell save dc and spell attack bonus.
