Vanilla Skyrim is very friendly to the player. Especially it concerns the endurance or the stamina. This mod will add meaning in its pumping and focus on the stamina to achieve victory in battle.

Endurance II:
- Stamina costs when a player attacks with a one-handed, two-handed weapons or a bow.
- Heavy armor slowdown the player (5%);
- The overload effect has been replaced by a slowdown (50%);
- The Fresh perk give a bonus to damage and block depending on the level of the corresponding player skill at 70% of stamina;
- Calculation stamina drain depending on the stats of the player's maximum health and stamina, as well as the carried weight. The more in your inventory items, the more stamina is spent on the attack.
- When your stamina to zero you are experiencing a slowdown and overload, your attacks do half as much damage.
- MCM menu for mod options settings.

The main effects that the mod adds are (OLD):
- The cost of the stamina for running, swimming. And the scaling of these costs depends on the weight of the equipment that you have. (I did everything I could to find the necessary functions in C64 to make this effect full-it should be tried. In endurance walking, the stamina is not restored.)
- The cost of stamina when attacking a weapon and its scaling depending on the corresponding weapon skill - the more skill the less the costs.
- When PC run in the stealth mode endurance reduce, it is depending on the skill of stealth and weight of equipment.
- Overload the player, as soon as the stock of stamina goes to zero you begin to experience the original effect of overload.
- Level of max stamina dependence of endurance costs in the above listed cases. Basically, this effect is scaled in level of max stamina 150, 300, 450, 600 and onwards that is, from the 150 level of max stamina, the increased effects of endurance costs begin.
- NEW power "Fresh", when you have 80% >= stamina - you get 30% damage and block for one-handed two-handed weapons and shooting depending on your skill in the appropriate weapon and block.
- NEW system for baf-debaf stamina rate. You will have 50%, 25% and -50%, -25% rate stamina on different levels of stamina reserve, by the principle of the more stamina the more its regeneration.
  During the creation of this mod, I spent a very long time looking for the right effect for endurance costs. The one that is now used is the most optimal in terms of work and complexity, which made it possible to accomplish all the tasks posed in mod.

Requirements:
Skyrim SE 1.5.50 and higher
SKSE
SkyUI

Compatibility:
- Absolutely compatible with other mods for battle or rebalance of the gameplay like the Ordinator.
- Mod with a similar idea will seriously affect the balance, not compatible.
- Smilodon - Combat of Skyrim - compatible. Patch in the options, you need to turn off Endurance II and customize stamina cost in custom settings MCM.
- Compatibility with different settings of the maximum skills level of the player is solved by changing the value of the global "EnduranceMSL". By default it is 100 for a vanilla game. If you are playing with a mod Skyrim Skill Uncapper, then simply change this global to your settings for the maximum value of the player’s skills level.
