// Here's a fun scripting example where players have to learn these magic spells to have cool effects.
// The world info has entries that should hopefully lead people to these spells and so that they can find and cast them.
// Can find the scenario at https://play.aidungeon.io/scenario/e982a8f0-a473-11ea-af38-d1932fa9d9e0
// I changed the spell names so it doesn't ruin the discovery if you play the adventure.
