Frost AoE grinding [ Out of date , needs to be updated . ] Frost AoE Grinding is a mage technique to kite and kill a large group of mobs at once . In many situations , killing multiple mobs at once can give more cash , loot , experience , and reputation than killing one at a time would yield . Because a Frost mage can kite multiple mobs through snare effects , frost AoE grinding can be done solo , whereas other AoE grinding techniques might require the help of a healer . Frost AoE grinding is doable by most mages from upper 20s all the way through to level 80 . There are two primary techniques : Improved Blizzard AoE Grinding uses the Improved Blizzard talent to add a snare effect to the Blizzard spell . Cone of Cold AoE Grinding uses the Cone of Cold spell , and talents such as Permafrost and Ice Floes to make the spell ' s cooldown shorter than the chill duration . One strong point of frost AOE grinding is that it becomes exponentially more powerful with even one or two pieces of Heirloom gear . and are both excellent choices while AOEing . and are also excellent boons to an AOEing frost mage as they increase the experience gain on each mob killed by 10 % . Combine both trinkets and either shoulder slot item and you have the ingredients for some very fast leveling with very little downtime . Talents and abilities . A few talent considerations are necessary to be effective at Frost AoE grinding . While any mage of any spec can effectively kite a few mobs at once , large packs of 5 or more need some specialized talents in the Frost tree to improve AoE snare effects . Talent selection generally depends on the chosen technique . There are several different techniques for frost AoE grinding , but most can be categorized by the primary snare spell used , Blizzard or Cone of Cold . With the changes to mage talent trees in 3 . 0 . 8 , the Blizzard Frost AOE method has become the superior method in terms of efficiency and effectiveness . Some notable changes : Blizzard can now crit and many Frost talents were revamped to provide a more generic benefit ( for example , Elemental Precision is now Precision . ) Some talent considerations are common for both techniques : When using Cone of Cold to grind , you won ' t want this talent because it will freeze single enemies and thus scatter them . This is a bad thing due to Cone of Cold ' s relatively small radius . However , when using Blizzard you might really love this talent . In addition to the extreme slow effect of an upgraded Blizzard , it will make whole groups of enemies practically stand still . There is no problem with scattered groups here because Blizzard has such a huge radius and also slows the foes much more than Cone of Cold does . Another advantage is of course that frozen enemies will take critical strikes from Cone of Cold or Arcane Explosion more often . One disadvantage , however , is that the unpredictability of this talent makes it hard to fully control mob packs . When using Frostbite you have to choose between your Ice Armor and the other armor spells for melee mobs will often freeze in place after hitting you while Ice Armor is active . . . which makes it quite complicated to get them all together . On the other hand it greatly increases your survivability especially on low levels . So if an enemy is frozen just lead the others to him . Most AOE Frost mages recommend steering clear of this talent in particular . Another talent to watch , similar to Frostbite . The unpredictable nature of when this will occur makes this another talent that is hard to recommend . Improved Blizzard talents . The Improved Blizzard technique makes use of the Improved Blizzard talent , which adds a snare effect to Blizzard , reducing the movement speed of anything hit by it . The general technique is to cast Ice Barrier , mount up , gather your targets , cast Frost Nova , Blink away , and finally use Blizzard on the pack to AOE down the mobs . With the changes to Blizzard - i . e . each wave now has a crit chance - one to two Blizzard ' s can down most same level packs . Further , some mages have enjoyed great success with Arcane Concentration . As Blizzard hits multiple targets simultaneously , it greatly increases the chances to proc clearcasting , making your next spell free - Blizzard has a high mana cost and this can offset that greatly , speeding up AOE times and freeing up mana for other spells . Cone of Cold talents . The Cone of Cold technique uses Cone of Cold almost exclusively . The spell normally has a chill duration of 8 seconds and a cooldown of 10 seconds , but with talents such as Permafrost and Ice Floes the chill duration can be made greater than the cooldown . This allows the mage to overlap snares indefinitely . To overlap Cone of Cold snares , the cooldown must be shorter than the snare duration . This is achieved by reducing the cooldown or increasing the snare , or a combination of the two , via two key talents : Summon Water Elemental talent . First , while in a defensive stance the Water Elemental will stop where ever you first attack ( or get attacked ) while NOT mounted . This means that while you are mounted and rounding up a group of opponents , the Water Elemental is passive , ignoring attacks and more importantly , following you closely . When you have rounded up the opponents tightly and cast Frost Nova , the Water Elemental will stop right in the middle of the group and begin attacking one of the enemies . The value here is that you might get a resist from one ( or more ) of the enemies on the Frost Nova cast . After blinking , target the enemy that resisted and command the Water Elemental to attack it . The enemy will be quickly pulled back into the group of frozen enemies as a result . This saves you from using up Cold Snap , rounding up the enemies , and casting Frost Nova all over again . Second , sometimes you may be in a decent area for AOE , except for the occasional caster that may be too close to avoid . Once again , the Water Elemental can take care of this situation . Target the caster before rounding up the group of enemies , then after casting Frost Nova on the group , command the Water Elemental to attack the caster . The Water Elemental takes the damage and you are free to cast uninterrupted . The Water Elemental is also great for finishing off a lingering enemy and will usually survive for several AOE engagements , so the two minute cooldown on recast is not usually an issue . The technique . Find a good spot . Frost AoE grinding works best on equal - level or lower mobs that only do melee attacks . Ranged mobs , such as casters and gun / bow users are not recommended because it is difficult to round them up into a neat pack , and their damage can ' t be avoided by kiting . Mobs should be in static camps or roaming close by to gather them up most effectively . The area should be generally clear of obstacles that will hinder line - of - sight , and any stray patrols that wander by that could spoil a pull . Frost AoE grinding requires a lot of space to kite the pack around . Know the area well , where obstacles are and how mobs will path around them . It takes a bit of experimentation to find a good camp and become familiar with it . When grinding for experience , mobs should be equal level or lower . Higher level mobs have a higher chance to resist spells , and one resist can break up the pack and spoil the pull . If resists are a problem , consider a lower - level location , or pull fewer mobs at once . The gather . The first step , regardless of technique , is to gather the mobs into a tight pack . This is best done on a mount , but lower level players won ' t have one yet . The key is to aggro as many at once as possible and run in a circle , keeping the mobs in the center . After running in a circle for a while , the mobs will be in a tight pack on top of each other . Before gathering , use a shield such as Mana Shield or Ice Barrier if specced for it to reduce damage taken while gathering . Taking some damage is OK , because once they are in a tight pack and kited properly , any further damage is completely avoidable . Note that the farther you run from the spawn point , the more likely it is for a mob to break off pursuit and reset . To prevent this , circle around as close to the spawn points as possible . In some cases it might not be possible to get all the mobs in a single pack because they will reset . One possibility is to use Arcane Explosion to keep aggro , and use Blink to keep distance and continue to circle around the pack . Once a tight pack is established , dismount and cast Frost Nova . Improved Blizzard technique . The Improved Blizzard technique uses the Blizzard spell , talented with Improved Blizzard to add a significant snare . With 3 points in the talent , the snare reduces movement speed by 50 % , the most potent snare spell available to a mage . With Permafrost , the snare can be improved further to 60 % . Chilled to the Bone also adds an additional 10 % . After freezing a pack of mobs in place and moving to maximum Blizzard range , it is possible to channel two full casts of the spell before the snared mobs reach melee range . For non - elite mobs a few levels below the mage , this is often enough to kill them all . However , extended kiting is more difficult with this technique as it is more troublesome to keep the pack indefinitely snared . Cone of Cold technique . The Cone of Cold technique primarily uses the Cone of Cold spell ( CoC ) , properly specced so that the snare debuff lasts longer than the spell cooldown . This technique is most effective for higher level mages , and especially on groups of elite mobs . With the Improved Cone of Cold talent , CoC has better mana efficiency than Blizzard , meaning the mage can kite higher - HP mobs . The most common thing that can go wrong is Cone of Cold misses one mob , either because it is out of range , or it resists . When this happens , use Frost Nova before the pack becomes too spread out . The pack will always spread out a bit , so it ' s necessary to reposition . On a miss , the loose mobs will move towards the mage , and generally make a straight line . Reposition ninety degrees to this line so that the mobs are roughly all the same distance from you . At this point , Cone of Cold will be on cooldown , so get range and use improved Blizzard as a snare until the mobs are in CoC range again . Note that this will only work with one or two points in Improved Blizzard ( not three ) , as discussed above . If the Frost Nova also resists , then Cold Snap if specced and try again , or use Summon Water Elemental and cast its freeze spell . If using the water elemental , be sure to put it on passive or it may attack a single mob and probably break the freeze . If resists continue to be a problem , consider grinding a lower - level camp or pull fewer mobs . If at max level , then consider wearing more spell hit gear when grinding , or speccing Precision .
