While the Monster Hunter spells now show up in their list properly, some of them do nothing upon casting.
For instance, casting See Invisibility or Improved Invisibility on yourself will do nothing, as will Magic Circle against Evil.
When I tried to cast Greater Magic Weapon on a shortsword, the message said that that the object was not a valid target.
Spells that do work: Ultravision, Alarm, Light, Disrupt Undead, Light Step, Ultravision, Knock, Dispel Magic, Diminish Undead,
Halt Undead, Remove Curse and Hold Monster.
