I forgot about it too, until I saw it mentioned in another post.
It is easy to forget about this quite powerful spell since in KBAP you rarely get to use it in the latter stages of the game since by that time you really don't have any battles wherein a level 1-4 unit would give you problems; only level 5 units give you pause, and Target doesn't work on level 5 units.
And then came the Goblin Shamans.
