Ghoul

Ghouls don't run in low health, can't be pushed and they move objects.

This kind of undead is found usually in groups and can be dangerous for inexperienced players. Only fight them while wearing good equipment or keeping them at distance, otherwise their melee combined with lifedrain can do a lot of damage. They are commonly used as a summon for knights in training. Unlike most of their undead counterparts, Ghouls leave bloodstains when damaged.

They should have good skills to fight these creatures. Don't fight more than 3 at once unless you have 50/50+ skills. Also keep in mind that you cannot block their lifedrain without a garlic necklace.

Strategia — mag

Ghouls are good creatures for experience, their loot is very good when comparing with the time and mana used to kill them. Use Heavy Magic Missile or a Summon Creature (Monk) to hunt them.

It's possible to defeat ghouls at a low level, with low skills and ample running space, even the lowest level paladins can hunt them.
