Bosses are 2 to 5 times stronger than minions
Bosses level with the player

Enemy races have various buffs (health regen, +stats, no limb damage)
Bosses (most) accompanied by a skull icon next to its health bar
Compatible with mods changing general enemies

My mods to use together
Vaultman Perks - A Minimal Intrusion Perk Overhaul
Vaultman - Enemies and Bosses
Vaultman - Hardcore Settings

Requirements
All DLCs

Compatibility
Compatible with anything except those changing races and boss NPCs mentioned below.
Mods that changes non-boss NPCs are compatible.
For mods that edit the same race/npc covered by this mod, you can either load this one after others to enjoy my benefits, OR vice versa. It's usually okay to do so. However, sometimes unexpected issues arise. Please make your own judgement.
