Notes
A banshee, according to the irish myth, is the spirit of a deceased woman that is an omen of death or generally a messenger from the underworld. On Tibia, a banshee is a beautiful woman who has been betrayed and committed suicide, but death did not accept her sacrifice and sent her back.

Strategy
To all vocations it is recomended to use a Garlic Necklace.
Mages should use an energy or ice rod/wand combined with ice or energy Strike. Be ready to follow them, as they run in fairly low health, but watch out for a second attack as they can heal (and return) relatively quickly. Trying to take on more than one banshee at a time can be dangerous and is not recommended for lower levels. Demon Skeletons can be useful to help blocking and killing.
Paladins need space to run and use healing spells to remove paralysis.
Knights should use a two handed weapon to kill fast, most damage you will take come from life drain (not blockable).
