| Spell DC's are based on the spell level + your main spellcasting score (charisma for sorcs, intelligence for wizards, wisdom for clerics etc) + 10
So if you have an 18 charisma and you're casting a fireball on a horde of kobolds. Each of those kobolds has to make a reflex save and meet or exceed a roll of 17, this is because you have a +4 charisma, and it's a third level spell, so 3 + 4 + 10 is 17. |
