Clairvoyance

Clairvoyance is a spell added by Electroblob's Wizardry.

With this spell selected, sneaking and right clicking a block will remember its location. Casting Clairvoyance will then create a path of particles from the caster's position to the remembered location, which lasts for. The spell cannot be cast if no location is remembered, the remembered location is in another dimension or if no path less than 256 blocks long could be found.

Wand Range Upgrades increase the maximum length of the path, and Wand Duration Upgrades increase the duration of the particles.
