Damage gear

From WoWWiki

See also: Formulas:Plus damage and Plus healing

There are two types of damage bonus gear: those that say "increases damage done by Y spells and effects by up to X" and those that say "+ X Y Spell Damage". Both are the same functionally, the difference is that the first can affect multiple schools (mage spells, healing spells), and the second is always one school or type of effect (shadow, fire).

Note that channeled spells and DoTs that have their total damage spread out over several ticks has the damage bonus spread out as well. A Rank 3 Arcane Missiles spell with a +10 bonus item, for example, would gain a bonus 2 damage to each tick of damage.

The bonus damage to a spell is actually dependent on the casting time of the spell affected by this bonus.

• 3.5 Seconds or More - full bonus listed
• 3.5 - 1.5 seconds - (cast time)/3.5
• 1.5 seconds - Instant Cast - Considered a 1.5 second cast (due to global cooldown), so 1.5/3.5 or 43%
• If a spell has both a damage and a healing effect, the bonus will be split between the damage and healing portion of the spell
• AoE spells are further divided by three.
• All these conditions stack, so if a spell is both AoE and channeled, it will split 1/3 of the total bonus across all it's ticks

The casting time for the purposes of this effect is the base time, before considering reductions due to talents, or increases due to debuffs.
