A Globule of Arcane is like a fragment splintered off from hitting a rock, or a chip from a lumberjack's blow, with Globules composed of arcane energy rather than a solid. They come from the Cube of Arcane when someone harvests it for magic or from pieces cut from it. Harvesting a Sphere of Arcane for Orbs of Arcane will produce 100 to 400 fragments of arcane energy which quickly coalesce into a wavering sphere that has the viscosity of mercury at first, but then hardens over time to something akin to an ostrich egg. They can be used as weapons, releasing all their contained energy on impact and unleashing a dust that can cause havoc with magic, or they be used as vessels of arcane energy.
A full-size Globule of Arcane holds 30 spell levels of energy. This can be used by an arcane caster to recover spells previously cast. Each time it is used in this fashion, the Globule gets smaller and its energy potential declines. Once it gets to 1 spell of use before disappearing, some decide to keep what now looks like a modest pearl. It is used in decoration or added to some trinket or jewelry. In Tamlêrran, some wizard-governors wear necklaces of 6 to 12 of them. This is done out of vanity and show of great wealth. Globules of Arcane are extremely rare, requiring an item of artifact-like power to even cut into a Cube of Arcane.
The stored spell energy of a Globule of Arcane also serves as a direct weapon. It can be launched from a sling or hurled. It delivers 2 hit points of damage per spell level left in it, with a fully charged one delivering 60 hit points of arcane damage (wearing no magic - Reflex 20 for half, wearing magic - Reflex DC30 for half). The area of effect is a 5' globe. On detonation the Globule releases dead magic dust that nullifies the magical properties of all magic items on the targets until it removed (jumping in water removes immediately, spending 4 rounds brushing it off, or being in an area of strong wind will remove in one round). The dust become inert after 4 hours.
