Wand Focus: Fire (Thaumcraft 4)

Upgrades

 * Frugal - Thus upgrade reduces the vis cost of activating the focus's powers by 10% per level.
 * Potency - This upgrade increases the damage or strength of the focus's powers. The exact damage increase varies from focus to focus, but is usually about 20% per level.
 * Alchemist's Fire - This increases the potency of the elemental fire in the focus. Any targets set alight will burn for much longer.
 * Fire Ball - The focus will now produce an explosive ball of fire you can hurl at your foes. The Alchemist's Fire upgrade causes it to also set the ground aflame around the point of impact.
 * Fire Beam - The focus emits a narrow stream of fire instead of a wide swathe. It burns through anything it touches inflicting massive damage. Having an Alchemist's Fire upgrade will set blocks on fire.
