Legend
Correct, Pages from the Mages V in issue 100 page 13 which was 1e AD&D. Later updated to 2e in Forgotten Realms Adventures and then in the Wizard's Spell Compendium Volume 1.Yeah, it appears in the Wizard's Spell Compendium in the 1990s. The source, I believe, is one of the Pages of the Mages articles that ran in Dragon, considering it is listed as being in a specific wizard's spellbook.
Bladethirst (Alteration)
Level: 2
Range: Touch
Duration: 1 round
Area of Effect: Blade(s) of one weapon
Components: V, S, M
Casting Time: 1 round
Saving Throw: None
Explanation/Description: By means of a pinch of powdered silver, adamantite, or mithral, and at least a drop of (human) blood, the caster endows the blade (or blades) of an edged weapon with a + 3 bonus to hit on the following round only.
This temporary magic is visible as a blue-white glow about the weapon, and fades when the blade strikes a creature or the spell expires, whichever first occurs. The weapon must be touched by the caster, and can be wielded by the caster or any creature but if it is thrown, cast, or launched (i.e., a fired missile weapon such as an arrow), the + 3 bonus will not apply. (Note that an arrow held to stab like a dagger would gain the bonus.) The weapon does not gain a + 3 bonus on damage, but is considered magical for to hit purposes on the round following spellcasting, and if it must make a saving throw during that round, it gains a + 3 bonus on the save. (Polearms such as spears and halberds are edged weapons, but spiked weapons such as a flail or a morning star are not.)
