Upgrades

 * Frugal - Reduces the vis cost of activating the focus's powers by 10% per level.
 * Potency - 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.
 * Bat Bombs - This upgrade will make the summoned firebats even more volatile. They always explode when they contact their target and the explosion will be a lot more potent than normal.
 * Devil Bats - With this upgrade applied the summoned bats are larger, tougher and nastier. They will never explode, but keep attacking their target till it expires or they are slain.
 * Vampire Bats - This upgrade changes the summoned bats into vampire bats. Not only will they suck the life out of their target to replenish their own, but some of the stolen life force is given to their summoner.
