Starting now my 7DRL: Wizards’ Duel.
In the game you are one of two rival wizards. You have to fight and make pacts with different spirits to unlock new combination of spells to finally challange and defeat you rival.
For example: once you make a pact with the spirit of fire you can use it as an element of your spells and combine it with other spirits to discover additional effects.
Good luck to everyone, see you in 168 hours!
