Farstrike a useless spell?

[Endoperez]

With a high-srength caster, I quess Farstrike could punch through even heaviest armor. With cheap items like Boots of Giant Strength or Halberd of Might, the damage could become pretty high.

EDIT: I tested it, and while the damage can be good, the low precision really hurts. If there were giants with access to Farstrike, it would occassionally have spesific uses even in the very late game, but as it is, it's just a low-level spell. Against heavily-armored enemiest, it's better than Stone Shards.
