[Spell] Dryad Allure Rathril [Secs] 3.0 [Mana] 40 [Skill] 52 [Effect] 
Attempts to charm a humanoid creature. More powerful creatures are more difficult to charm, but once charmed they will obey your commands like a tame pet. In general, all non-named creatures vulnerable to a repond slayer can be charmed. Charmed creatures do not need to be fed. If you fail to charm a creature it will anger and attack you. There's no reason to attempt to charm it again; creatures that are in combat cannot be charmed.
