Wand Focus: Primal (Thaumcraft 4)

The Wand Focus: Primal is a wand focus added by Thaumcraft 4. Holding right-click with it equipped will hurl an orb of primal energy. The orb explodes on impact, and has a small chance to cause other effects, such as creating taint, or a node at the impact site. Its base vis cost changes every tick.

Upgrades

 * Frugal: This upgrade reduces the vis cost of activating the focus's powers by 10% per level.
 * Seeker: This upgrade makes the orbs created by the primal focus seek out the nearest living target and not wander all over the place. This makes them a lot more stable, which also means they won't do anything unusual beyond exploding.
