The best part about Noita system is that it’s not all about what effect the spell will have but also how that spell will behave. For instance if you have a “rock” spell then the effect is just that, it spawns a rock. But if you add a “homing” modifier to that rock you no longer have just a rock, you have a rock that seeks out and kills pretty much every common enemy you find. The effect stays the same (rock is spawned) but the behavior of the spell changes (now seeks out enemies).

For comparison Morrowind also had a pretty awesome spell creation system, but that system was almost entirely about effects with very little impact on how the effect behaves (self target vs touch vs projectile). The extra dimension of the Noita system IMO really sets it apart from most other magic systems in different games.
