I've only recently found this mod and have been playing around with it for the past 2 weeks, and while I have found no issues with the mod itself and am able to produce a wide range of spells there is one part that I feel could be changed.
The loopcast bullets only cast a spell 4 times per second whereas the exosuit leggings cast a spell 20 times per second, the 4 times is useful for some spells but the ability to cast a spell 20 times per second with the cad would also allow for more varying spell abilities.
I understand that there is a significantly higher material cost for the leggings over the original loopcast bullet and so I was thinking maybe have the other varied ones cost more, like the 20 per second one requiring an ivory ingot instead of iron.
Either that or adding a later level trick that allows you to change the tick delay between each cast, with the default setting being 4 ticks.
