Shark bolt

From Ardrana

Use of the shark bolt spell creates one or more bolts of water, each the size and shape of a small, dark brown shark. Once the spell is cast, each shark bolt "swims" directly from the caster's hand. Each bolt pursues its target until striking or until traveling beyond the range of the spell. Concentration is unnecessary; the bolt pursues the target creature as long as the creature was visible to the caster at the spell's casting and does not escape by magical means. Any physical barrier that completely blocks the passage of a bolt will cause it to splash and dissipate harmlessly.

The bolt can be attacked and reduced in strength. If struck by a physical weapon of any sort, it loses some of its volume as well as its power. A bolt dissipates if struck a second time.

Note: Shark bolt originally appeared in this form in Dragon Magazine 187 for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
