Banish

Banish is a Shadow-based crowd control spell, which makes an elemental or demon invulnerable for a given period.

Tips

 * If you are having problems with Banish breaking early then cast Curse of the Elements first. This will cause Banish to have a much greater chance of lasting its full duration.
 * Recasting Banish on a target already afflicted by the spell will cancel the spell's effect.
 * Banished mobs can be affected by a Voidwalker's Torment and Suffering abilities (and possibly the similar hunter pet ability as well?).
 * Mobs can be Taunted during a Banish. Communicate to your tank when the effect is seconds away from wearing off, they will appreciate the notice as it will allow them to place a Taunt effect on the mob and keep it from running out of melee range.
 * As with other Crowd Control abilities, it can be useful to employ the "Focus" system, especially using a macro such as this one.

Tricks

 * May be used against another warlock's minion.
 * May be used on elementals such as a mage's, a shaman's and s, and a druid in Tree of Life (druid ability) form.
 * May be used against warlocks using Metamorphosis.
