Ghost (Oblivion)

Ghosts are undead spirits that cannot be harmed physically and can be damaged by magic, silver, daedric, enchanted weapons (the weapon does not need to have charge to be effective), or hand to hand (Journeyman) combat. Though ghosts are usually enemies, not all are hostile, some may even send you on quests. A good way to tell NPC ghosts from hostile ghosts, is by looking to see if they have legs. If they are just a floating figure and do not look anything like a human would, they are most likely dangerous.

Tactics
Ghosts will only attack with ranged and melee magic; most of the time they'll use frost damaging spells.

Drops

 * Ectoplasm
 * Sometimes wraiths drop swords

Strengths

 * Immune to most normal weapons
 * Immune to normal arrows

Weaknesses
Ghosts are particularly susceptible to Shock Spells and Staves. If you don't have any shock spells, you can use silver and daedric weapons at a stretch (or fists if you are a Journeyman or higher in Hand to Hand). Otherwise, running is a useful strategy.
