I have been playing Skyrim for a while now and have yet to see a detect life enchantment in shops or in random loot. just wondering if there is actually a detect life enchantment as it was my favorite in oblivion.
The Skyrim devs didn't really implement "detect *" into the engine. Instead they cut corners and created a area of effect attack that leaves a glow afterwards. Consequentially you actually have to script into the game your own detection mechanism from the ground up. It has to attack every creature conditionally depending on its reaction to player.
