Dancing lights

Dancing lights was an evocation or alteration spell that produced levitating lights that could move at the caster's direction.

Effects
All versions of this spell produced up to four floating lights that could be made to appear as torches, lanterns, or as orbs vaguely resembling will-o'-wisps. They could also be combined into a roughly man-sized glowing humanoid shape reminiscent of a being from the Elemental Plane of Fire. The lights were fairly dim, casting as much light as a regular torch.

The oldest versions of this spell had a minimum range of 150 ft (46 m) and a minimum duration of two minutes, both of which could be extended by casters of higher level. The separate lights could move independently and, once set in motion, did not require concentration by the caster. A newer version had a minimum range of 100 ft (30 m) and a duration of one minute. The lights had to remain within a 10-ft (3 m) radius sphere. After the Second Sundering, this spell had a fixed range of 120 ft (36.6 m), one minute duration, required caster concentration, and each light had to remain within 20 ft (6.1 m) of one of its siblings.

All versions of dancing lights winked out if they exceeded the range of the spell. This spell could be made permanent using the permanency spell.

Drow
Drow elves could cast this spell once a day as a spell-like ability. Some drow also learned to combine this power with their other abilities of darkness and faerie fire to produce even stranger effects.

Components
All versions of this spell required verbal and somatic components. One version did not require any material component, while all the others needed a pinch of phosphorus or wychwood, or a glowworm.

History
The spell was attributed to Netherese arcanist Brightfinger in -1647 DR and was originally called Brightfinger's dancers.
