(For those who want to use this mod to make shouts cost Magicka, use this mod instead. It uses SKSE and is a better option overall.)

This is a port of this mod which, despite the name, offers options for magicka, stamina, or a mixed cost to all attributes and not just a health cost. The closest thing to this is a number of mods which allow usage of attributes to short shout cooldown after the fact, but I preferred a more direct style of casting. He has open permissions so I figured I'd port it over and give it a better name for what it grew into.

This mod works by using a script to record the cooldown when you shout, subtracting the cooldown out of your choice of attribute (don't worry, this won't kill you if you choose the health costs), then reducing the shout cooldown accordingly. This has the interesting effect of making it so that, if you shout and the cost is greater than your attribute pool, it'll actually trigger the remaining cooldown left after subtracting from your pool, and stops that attribute's regeneration for the duration. Its usage of a script does mean it's affected by script lag, so if you run a very script heavy setup you may notice delays in its functions. It has little to no load on its own though.

If anyone has ideas for different options to decide the cost I believe I understand the script enough to make edits. Feel free to make requests regarding tweaks of that nature.
