Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods How & Where will I start making a small Adventure?

When you create a profile in the game, use the kickstarter code listed in the Vault (can be used multiple times, if you want to use different profiles to keep different playthrough separate, etc). In a game started in that profile you should have a summon spell in the 'special' category of your skill window, along with Staff of Magus. You should have gotten an email about choosing a summon before release.
