Problem

In the base game crit damage hit for a low amount and doesn't scale, it was also limited to swords and bows for most of the game. With all of the relevant perks acquired you only did about 30 damage at most, which isn't great when your weapon is dealing around 100 damage per strike normally.

Solution

All weapons now have a 5% chance to critical hit. Crit damage now scales with weapon skill, perks, fortify damage enchants, alchemy potions, smithing, vanilla racials, quest buffs, and power attacks.

For example, lets say your sword has 10 base crit damage. Raising your weapon skill can raise this to 15. Get all the relevant perks and it becomes 90. Power attacks double your multiplier for a 180 damage crit. If you want to use enchanting to buff your weapon you can get it to 1440 damage if you have 800% of it. If you sell your soul to satan and then chug an alchemy potion you can reach 11520 crit damage with an 800% buff. If you want to finish off the insanity loop and add in smithing then the final number becomes 17280 at 100 smithing. Now you can 1-shot Akatosh himself. Congratulations, you've spent more time in town crafting than actually playing the game.
For normal attacks the formula is: base crit damage x 1.5 x 6 = crit damage. This translates to critical hits dealing 150% of your weapon damage when you crit instead of half base weapon damage.

The 1.5 in the above formula represents your weapon skill and scales at a 0.5% crit damage ratio for each point of your weapon skill. This can go past 100 with enchantments or mods but in the vanilla game 100 is the soft cap.
The 6 is the basic attack modifier which accounts for weapon damage buffs from perks. This ranges from 3.6 to 6, for power attacks this would double to 7.2 and 12.

Enchanting and alchemy add two more modifiers onto the above formula and scale at a 1:1 ratio. So if you wanted to calculate your damage output you would get: base crit damage x 1.5 x 6 x R x R = crit damage. For additional buffs such as the orc racial or seeker of might just keep adding multipliers and you'll get your answer.

Smithing adds +1 damage to your base crit damage for every 20 skill you have in smithing, smithing enchantments, or smithing alchemy potions. This is the formula: (base crit damage + R + R + R) x 1.5 x 6 = crit damage.

The reason the damage scales with smithing skill instead of how far your weapon is tempered is because at the moment I have no idea how to check for it, otherwise I would have gone with that route.

(This is an old mod that wasn't designed to work with other attack speed mods. In the next couple months or so, it's getting an update to fix any possible compatibility issues that may arise. Until the update, use common sense with your installed mods.)

Problem

In the base game bethesda forgot to set your attack speed to 1 and left it at 0. Instead of fixing this problem and hard coding it to 1 or using some sort of game setting they opted to just use a work around which caused more problems than it fixed.

Starting at 0 is a problem because you need a 100% buff before anything beneficial is applied to you and anything lower than 100% actually slows down your attacks. For some reason 0 = 1 as far as the game is concerned. That allegedly 30% draw speed buff in the archery perk tree is actually 130%, the same goes for other buffs, they're much higher than they should be. This results in attack speed effects not stacking properly and turning you into some kind of speed addict with a blade whenever you have more than a single effect on you.

Attack speed debuffs don't work either because you start at 0 unless you happen to have a buff on you at the time the debuff is applied.

Solution

I changed the base attack speed to 1 and made the changes accordingly to every attack speed buff in the game so that they play nicely with one another. This is distributed through combat perks.

Attack speed buffs from other mods may or may not play nice with the ones from this mod, it all depends on their settings.

Shout Attack Speed Changes

• The elemental fury shout should work with all weapons now, enchanted or not.
  

• The elemental fury and battle fury shouts now function with ranged weapons at half the effect.
  

• Battle fury now buffs any non hostile npc near you when you use it, living, undead, whatever. Start making friends.
  

• The duration for both shouts was changed to 20, 25, and 30 seconds.
  

• The cooldown period for both was changed to 30, 45, and 60 seconds.
  

• Battle fury had its effect magnitude lowered to 15%, 25%, and 35%. This was done because battle fury outclassed elemental fury by leaps and bounds, now they're more even. Battle fury is equal to elemental fury with at least 2 friendly npcs near you and outclasses it when you have a group of 3 or more friendly npc's.
  

• If the npc doesn't have the weapon speed fix you don't need to worry about nerfing their damage output, the fix is applied to npc's when using the shout. Even random farmers can become killing machines now with battle fury active.
  

You get movement speed buffs or debuffs based on your equipped weapon. You gain 10% movement speed when above 50% stamina. You gain 5% movement speed when in-between 25% and 50% stamina. You lose your buff when below 25% stamina.

Depending on your choice of weapon you'll either gain a buff or debuff to your movement speed. Dual wielding weapons has an effect on this buff and will change the buff values depending on what combination of weapons you're using. If you manage your stamina well, you won't experience the negative effects from heavy weapons.
