A number of monsters (e.g. Dak, Hugo, Yggaz) cannot be teleported with wands of teleportation. However, the Teleportation spell and the Teleport Other mindcraft power work fine on them. Particularly strange in the case of Hugo, as he is angered by futile attempts to teleport him with a wand of teleportation, but is indifferent to successfully being teleported by the spell.
