Gameplay Notes[]
The scariest thing about shadows is their strength drain. It can only be removed with a Lesser Restoration spell or better (you can have priests in-game "heal" you and that will also remove the strength drain). Wearing an Amulet of Health or Greater Amulet of Health makes you immune to ability drain and that makes shadows mostly harmless.
The other notable thing about these is they have a 50% concealment bonus so you'll miss twice as many attacks as you would against another enemy with the same armor class. The only solution against concealment (for attacks that require an attack roll) is to have the Blind Fight feat, which effectively reduces enemy concealment by half. And don't forget about their immunity to non-magical weapon.
Before patch 1.22 a shadow could be summoned with Create Greater Undead at caster level 15 or below.
