And the ability to turn any npc with 100% effectiveness. The other has ae paralyze for 10 seconds, a single target paralyze for 10 seconds, ability to charm npcs and the ability to attack and use objects while invisible.
It also has the ability to keep dead thralls indefinitely up to level 80. Thats almost like giving yourself a mehrunes dagger effect no matter which weapon you use. One has a 5% chance at procing a 500 damage ability using melee weapons. Personally speaking though, they make me cringe abit balance wise. Honestly, both those mods linked sound good.
