Nystul's Radiant Baton

When the wizard casts this spell, it summons into the caster's hand a slender baton formed from energy drawn from the Quasi-Elemental Plane of Radiance. The baton can be one of the seven colors of the rainbow as the caster chooses. The attack form of the baton corresponds to the color chosen, being similar to the attack of a radiance Quasi-Elemental creature, as follows:

Red Baton: cold energy (+1 damage to fire-based creatures, no damage if cold-based);

Orange Baton: heat energy (+1 damage to cold-based creatures, no damage if fire-based);

Yellow Baton: acid damage (save vs. spell to take no damage);

Green Baton: neutralize poison (as 4th-level priest spell);

Blue Baton: electrical energy (+10 damage to metal armored enemy);

Indigo Baton: undead specific (only undead are harmed);

Violet Baton: vegetation specific (only plant-based life, including fungi and molds are harmed).

The color of the baton is chosen during casting, and cannot be changed thereafter. Creatures are allowed no saving throw vs. the effects of the radiant baton. The baton automatically hits any creature that successfully strikes the caster in that melee round; otherwise, the caster's THAC0 determines a successful strike on an enemy. When a hit is scored, the baton inflicts a base damage of 2d4 points, plus one point of damage per level of the caster (to a maximum of 2d4+10). The type of damage corresponds to the color of the baton.

The material component is a crystal prism, which shatters at the conclusion of the spell. The spell also requires a set of seven small, silver rods, which can be reused.
