Glad that you found that balance of typing/playing to be a fun challenge. We chose to not give away too much about what the spells do as we liked the idea that they needed to be used to undertand them. I see how that might've been confusing with the Miasma spell though; it's essentially just a poison cloud that enemies take damage from when they go through it.
Thank you so much for your kind words, it means a lot :)
