'''Molt Thorn''' is a level 42 [[rare mob]] [[bog beast]] found in the [[Swamp of Sorrows]].
'''Arcane Blast''' is a [[mage]] spell that deals direct arcane damage, with increasing damage levels and mana costs when cast in succession. With careful management, the mage can use this spell to trade off [[DPM|damage per mana]] versus [[damage per second]].

Each cast will apply a debuff "Arcane Blast" to the mage that increases damage done by the spell but increases its mana cost. This debuff will stack up to three times, and lasts 3 seconds. The values are listed below:

==Notes==
 
This spell is available at level 64 (and therefore, only available to players with the [[Burning Crusade]] expansion).
 
 
For characters level 70, arcane blast's base damage increases to an average of 720, up from the 700 it was when you first learned it. This happens with other mage spells as well.
 
 
The 3-second debuff duration is meant to make the spell interesting in a rotation along with [[Arcane Barrage]]. If both are rotated, the Arcane Mage can achieve high DPS while not having to deal with the debuff, as there won't be time to refresh it between Arcane Barrage-Arcane Blast cycles.
 
 
It had been reported that mana increasing modifiers such as arcane power or 2/5 [[Tirisfal Regalia|mage T5 set]] bonus add to the % listed in the table above rather than multiply the mana cost listed in the last column, meaning they get more "relatively effective" as you stack the AB debuff higher. The practical result means that if you're going to spam AB with 3 debuffs stacked for some parts of the fight due to excessive mana supply, it's best to do it during arcane power uptime, as the relative increase in mana cost is, at that time, lower than the relative damage increase, compared to what you would get if you used arcane power and arcane blast spamming at different timeframes.
 
 
==Talents improvement==
 
 
[[Arcane Subtlety]] will reduce the threat caused by Arcane blast. [[Arcane Focus]] will reduce the chance that it is resisted. [[Arcane Impact]] will increase the critical strike chance by up to 6% at max rank.
 
 
As with all mage spells capable of critical hits [[Arcane Instability]], [[Spell Power]], [[Molten Fury]], [[Playing with Fire]] and [[Shatter]] can increase the effective damage output of this spell.
 
 
==Tips and tactics==
 
The mana cost increase will run you out of mana VERY quickly. While debuffless Arcane Blast is fairly efficient in terms of [[DPM]], a single-debuff stack will already triple the mana cost for a very disproportionate DPM imbalance. Spamming this spell is very inefficient and virtually unsustainable even in the presence of such elements as [[Innervate]] and [[Replenishment]].
 
 
Luckily, its debuff is short and easily missed by casting a single spell in between Blasts (which will trigger the [[Global Cooldown]]). The spell you want to weave in between those Blasts is [[Arcane Barrage]], which is actually the ''higher DPS'' spell in the rotation (meaning you're actually weaving in Blasts between the Barrages) and has a 3 second cooldown. The full rotation is 4 seconds long (1.5 secs of Barrage [[GCD]] and 2.5 secs of Blast cast time), allowing for both Arcane Barrage's cooldown and Arcane Blast's debuff to wear off timely.
 
 
Arcane Blast is like Scorch (and unlike Fireball, Frost Bolt, and Arcane Missiles) in that it doesn't have a projectile animation. This makes the mage a bit less obvious in PvP combat as Arcane Blast won't leave a brilliant pointer back to the caster. Also, it's pretty hard to keep the debuff going as you'll hardly have time to sit around spamming 2.5 second casts (luckily for you).
 
 
==Patch changes==
 
* {{patched|patch=3.1.0|note=Stacking effect is no longer considered a Magic effect and will not be dispelled.}}
 
* {{patched|patch=3.0.8|note=This ability has been significantly changed. Arcane Blast now increases the damage of the next Arcane spell by 15%. However, using Arcane Blast itself does not consume the charge itself. Each time you cast Arcane Blast, the damage of Arcane spells is increased by 15% and the mana cost of Arcane Blast is increased by 200%. This effect stacks up to 3 times and lasts 10 seconds or until any Arcane damage spell except Arcane Blast is cast.}}
 
* {{patched|patch=3.0.2|note=The debuff was changed from a cast time reduction to a pure damage increase, and the mana cost penalty was massively increased. Debuff duration changed from 8 to 3 seconds.}}
 
* {{patched|patch=2.1.0|note=The Arcane Blast debuff can no longer be dispelled.}}
 
* {{patched|patch=2.1.0|note=A data error was fixed that was causing Arcane Blast to generate more [[threat]] than intended.}}
