The spellbook webtool creates spell and focus spell lists based on several filter boxes. Then you can print that list as a PDF. This is an advanced tool where you can filter spells in three steps.
You can select item by item or you can check the checkbox at the top of each filter. It allows you to select/deselect all of them at once.
When Show Heightened Spells checkbox is checked, you'll also see heightened versions of each spell. The spell description shows you the heightened version of the spell, with all calculations already made.
Cantrip Lvl select allows you to set the Level Cantrips and Focus Spells are heightened to. It also sets the maximum level shown for Cantrips and Focus Spells.
The spell matches table headers allow you to sort the rows just clicking on them. Moreover, the table has a first row with filters that allow you to filter the matches one step further.
Every time you make a new search, the table keeps matches from the previous table that were checked. That way, you can freely build a customizable spell list. You can also keep Focus Spells (if you checked those spells) from one search to another search made with normal spells.
First column table has checkboxes that allow you to select which spells you want to be printed out. In order to achieve that, just click on the PRINT button on the top right corner of the page.
You'll be able to change column display when printed sheet is displayed. Click on the top right button. You'll also be able to show/hide small boxes placed next to the spell names in order to keep record of used spells. Just click on the top right button
You can visit later this website and recover the list of spells you've checked after using the filters. Just click on the SAVE button to generate a unique URL that will lead you to that information. Now you can name the spell lists.
