My Level 18 Argonian assassin was recently decapitated by a Bandit Chief's battleaxe power attack.
For this feat to be performed by a player would require the "Devastating Blow" Two-Handed Perk.
Did this Bandit Chief have the perk, or a special NPC-only equivalent decapitation ability? If it was the perk, should I assume he had all the prerequisite perks as well?
Have others observed instances of NPCs (including companions) using perk-exclusive abilities?
