This mod is called Know Your Enemy 2 and it changes the way enemies in Skyrim have resistances and weaknesses to different types of damage. It adds 16 damage types and lets you customize the difficulty level. It also gives you a power to inspect creatures and learn their effects. The mod aims to make combat more challenging and balanced.

• The 16 damage types are: physical, fire, frost, shock, poison, disease, bleed, sun, holy, unholy, magic, arcane, psionic, ethereal, silver and daedric.

• The inspect power can be used on any creature to see its resistances and weaknesses as well as any other effects it has. It can be activated by pressing the shout button while sneaking and aiming at a creature.

• The mod is compatible with most other mods that change enemies or add new ones. It has patches for some popular mods such as Skyrim Immersive Creatures, Animallica, Beasts of Tamriel and more. It also works well with mods that change combat or damage such as Wildcat, Smilodon or Vigor.
