I don't know how to give a spell, but Blade Wind effect is just set damage (no str bonus), proper graphics, and 50 attacks/round. And precision -5, and limited to only be fired once or twice, and maybe something else for balance.

Most different damage spells can probably be modded in, but the special often can't. If a weapon already does it, it can already be modded, there are some weird things out there (eye loss from Vision's Foe, plague, life drain, paralyze, soul slay, enslave mind)
