We should definitely include more examples in the manual. They will be some of the first things we will include in the next version.
When a player casts a spell they make a sentence of at least two words of power (connected by prepositions as they wish). Their intentions are described inside that sentence, with only the words of power they have and as best as they can. It’s up to the GM to interpret the sentence and see if the intentions are described with enough details or if there are other consequences or effects they did not consider. The more words you say the more specific the spell may get, but higher is also the WIL you pay if you fail the save.
Having spells with only one word can make it very hard to judge situations for the GM. One word spells are also a bit too powerful in my opinion. The objective of the game is to encourage the players to use their creativity in combining words, having the limitation of at least two words helps with that in my opinion. One word is not enough and by including the second word they try to not make the spell do something unexpected, so maybe they include a third word and so on… Otherwise they would just use powerful one word spells all the time.
Hopefully this was helpful! Stay tuned for more updates to the game and thanks a lot for the feedback.
