Thanks for the feedback!
We thought about adding spell combinations later in the game. Like combining a Shield and a Fireball could give you a flaming shield that does damage to an attacker while shielded.
Having buffs based on their adjacency to each other though is such a great idea! Much harder to balance but we love a challenge 😂
Can't find you on Discord but if you're interested in seeing how we develop, we have a playtester email list that you can sign up for at shadowboltstudios.com.
Will try review Mouse Tower this evening!
