Filler

Commonly referred to in talent builds as marginally useful skills used to progress through the rest of the talent tree, or to get certain prerequisites for other skills. May also refer to a class-ability or spell which has a rather bland effect. Is implemented simply to ensure that players always have a ready (not on cooldown) button to click, or to equalize the number of spells divided on the various classes. Examples include the mage's Wizardry-spell and the priest's Darkness-talent.
