Ritual magic allows you to cast spells that you do not have memorized or don’t even know, by sacrificing several spell slots.

You will need to enter the ritual code above. The code is the first letter of your spell casting class name followed by the ritual number. Ritual numbers can be found from other help pages grouped by level.

Then you should cast spells that you use to charge up the ritual. You will need to use a minimum of spell level * 4 - your spell casting level in that class spell levels. Thus a level 3 wizard (maximum level 2 spells) will require 2 less spells levels to cast any wizard spell.

After you have powered the ritual enough, use the ritual book again and target the place or creature you want to cast the ritual at.

To succeed in the ritual, you will need to make a successful spell craft roll against DC 10 + spell levels needed. Each extra spell level used will reduce the DC by 1. After the ritual the spell is cast at the thing you targeted with the ritual book.
