Heroic mode Heroic mode Raid Lockouts are limited to raid size . For instance ; if you enter instance A and kill a boss on 25 man heroic mode , you are not able to engage any heroic man bosses with a 10 man group , in instance A , until the lockout has expired . Many groups will do progression with a 25 man group , then do a clean - up with their top 10 man group . This is not possible to do on heroic mode . If you kill one boss on heroic mode with a 25 man group , you cannot later clean up or progress on heroic mode with a 10 man group . Normal mode is not affected by group size lockout , and normal bosses can be killed by a combination of 10 and 25 man groups during any lockout period . Heroic mode dungeons are on a lockout timer much like raids , and can only be run once a day per character . Each dungeon is on an independent timer , however , so a character could run as many as 15 heroic mode instances per day . Heroic timers are reset daily at 11 : 00 A . M . server time for US servers , and 8 : 00 A . M . server time for European servers . In Warlords of Draenor . The level for Heroics has risen to level 100 . Along with new dungeons in the expansion , a Upper Blackrock Spire has been re - done and has a Heroic mode added . In Mists of Pandaria . The level for Heroics has risen to level 90 . Along with new dungeons in the expansion , a couple old lower level dungeons have been re - done or have had a Heroic mode added ( Scarlet Monastery and Scholomance ) . Heroic scenarios in Patch 5 . 3 . Patch 5 . 3 introduced Heroic mode scenarios . In Cataclysm . The level for Heroics has risen to level 85 . Along with new dungeons in the expansion , a couple old lower level dungeons have been re - done or have had a Heroic mode added ( Deadmines and Shadowfang Keep ) . Reports from blogs and forums indicate that the new Heroics will require more coordination , crowd control , focus fire , and threat management than players may be used to at the end of the previous expansion . In Wrath of the Lich King . With the second expansion , heroic mode was extended to raids . The key requirements were not included on instances , instead heroic mode is available to all players at 80 . The token system used in TBC heroics was considered successful , new tokens were added for the various " tiers " of wrath heroics and raids . For example , the same tokens drop in heroic 5 - players and the first - tier 10 - player raids , while a different token drops in the first tier 25 - player raids and second - tier 10 - player raids . A third token drops in second - tier 25 - player raids , and will presumably drop in the third - tier 10 - player raids when implemented . Before Patch 3 . 2 . 0 , Heroic mode raids , unlike their instance counterparts , did not dictate difficulty . Instead 10 - player raids were considered " normal " mode , and 25 - player raids to be " heroic " . Heroic raids are not intended to be " harder " than the 10 - player version of the same raid , instead simply tuned for the larger number of players . Heroic raids do still drop higher quality equipment than the normal - mode counterparts , by the logic that it is more difficult to form a good 25 - player group . The currency tokens dropped in each mode can be used to buy items of similar quality to the boss - dropped items . Patch 3 . 2 . 0 did away with this setting , other than showing up in achievements , in favor of the following : In Burning Crusade . Each of the 5 - player dungeons introduced in the " " expansion pack may be run on heroic mode if every member of the party has obtained the appropriate key . These keys are purchased from the faction quartermaster of the faction corresponding to the instance once reaching . At introduction the keys required , but this was reduced in later patches to allow easier access to the heroic modes . Magister ' s Terrace , which was introduced later with patch 2 . 4 , did not use a purchased key . To obtain this key players needed to simply complete a quest which involved killing the final boss of the instance in normal mode . Some heroic mode instances share loot with their normal - mode counterparts , while some do not . For example , items that drop in a level 70 normal instance like Shattered Halls will also drop in the heroic mode . However a lower - level instance like Hellfire Ramparts will have completely different items in normal and heroic mode . For the instance where loot is shared there are also additional items that only drop in the heroic mode . These items are of higher quality than the other items . Each boss in a heroic dungeon may drop an epic gem . The last boss always drops one epic item in addition to a Badge of Justice . Common requirements . In heroic mode , all instances get a lot harder , and most mobs have their damage increased and bosses often having their damage and health increased . Many of the following are stats commonly accepted by PUG heroics ( guild heroics may be higher / lower depending on the nature of the guild . ) Tank . Generally , tanks should have enough dodge / block / parry and life combined to be healed efficiently , but not constantly . Note that 5 - player - heroics healing is based upon healing the entire group , unlike 10 - or 25 - player - raid healing where tanks may often have a dedicated ( or 2 - 3 ) healer topping them off . In , tanks are usually expected to have at least 120K health un - buffed ( yes , the numbers got sort of out of control in Cataclysm ) , but health is less important now in level 85 heroics than it was in the past . Damage mitigation is more important as well as having the right timing and tactics . Usually get as much mastery as you can for heroics , and balance out dodge / parry ratings for maximum avoidance . Good targets are 25K armor , 10 % dodge , 10 % parry , and 30 % block . Maxing your hit / expertise is controversial , but most agree it isn ' t necessary . In , a tank should have 21k health un - buffed and 535 Defense . Wrath heroics are noticeably more difficult in boss encounters as well as the requirements for crowd control and group coordination . For , a tank should have at least 10k ( 10 , 000 ) health un - buffed and 490 Defense rating ( combination resilience , in which case defense is still preferred for mitigation ) . Healer . For , the way the various healing classes work have now diverged enough that any generalization about needed stats has probably become useless . Investigate level 85 normal and heroic healing prep guides for the class and talent spec you plan to heal with . For , a healer should have between 1 , 600 and 1 , 900 spell power , 230 ( while casting ) and 15k mana ( unbuffed ) to heal effectively in heroics . However , healer gear / stats are often greatly dependent on the tank . If your tank has 21k health and your healer has a low spell power , or low 5k mana , your healer will not be able to heal the tank quick enough , or for long enough . But if the healer has 1 , 500 spell power and 12k mana , but your tank has < 21k health , or is below 535 Defense it ' s not going to matter , because the tank will die too fast . A good healer has more than 14k mana : this is preferred for boss fights , and for efficient running ( most people geared for heroic aren ' t willing to wait after every mob for a mana break ) . Also try to aim for about 400 + mana regeneration when out of combat , and at least 230 + whilst casting ; this helps a lot with efficient running . Though less important than the above , health is also a vital factor , especially on low - armor healers , especially priests , who can be hit for 14k ( non - crit ) damage in some heroics ( e . g . Hammer of the Righteous , see Eadric the Pure ) . Strive for at least 16k + health ; and for paladin s and shaman s , a shield , which really aids with survivability . For , a healer should have between 1 , 000 and 1 , 300 spell power to heal effectively in heroics . Crowd control . In , crowd control has become very important again . For heroics there is no specific advice to give beyond , use all the CC techniques at your disposal unless the encounter has some more important task for you ( AoE , de - curse , misdirect , etc . ) In , most heroics do not need any form of crowd control . Correctly geared tanks can generate enough threat to hold the attention of multiple mobs , and the damage is low enough to be relatively easily healed . If crowd control is requested , Mage s are the most effective , because of the usefulness of Polymorph . Rogue s and Retribution paladins are the next best CC , with hunters ' Ice Traps and the Shaman Hex being last . If played correctly , all are viable forms of CC , and depending on the DPS output of your group , you may only need to incapacitate the mob for 10secs , making traps as efficient as Polymorph . DPS . All classes have a strong DPS spec and with Dual Talent Specialization , even players who normally heal or are tanks can have a second spec just for DPS . With for casters , a good round target to reach is 6K spell power . For melee / ranged DPS somewhere around 10K attack power is a good target . Caster DPS , should aim to have 1 , 500 + spell power ( absolute minimum ) ; and Melee / Ranged DPS , 2 . 5k attack power . Most classes should keep their health above 16k to avoid being one - shotted ; and casters should aim to have mana above 15k as well , so sustained DPS can be used on mobs and bosses . Daily quests . Patch 2 . 3 . 0 introduced daily quests for heroic dungeons . These daily quests , referred to as " daily heroics " , involved killing the final boss in a dungeon on heroic mode , and gave additional in or in and money as a reward . The daily heroic quests were removed in patch 3 . 3 . 0 , but daily heroic quests still exist . Weekly quests . Patch 3 . 3 . 0 introduced weekly raid quests and removed daily heroics . The reward is Justice Points and some money . Relative dungeon difficulty . heroic mode dungeons require you to have an average of item level 329 gear for you to be able to queue for them . This average of item level increases with each subsequent expansion . Relative difficulty in Cataclysm . In , heroic mode dungeons have the following relative difficulty . Relative difficulty in Wrath of the Lich King . In , heroic mode dungeons have the following relative difficulty . Heroic Mode ; Violet Hold , located within Dalaran , is commonly considered the easiest of all Northrend Heroic Instances . This is because it can be completed in under 20 minutes on average by those with even minor Heroic Instance Skills . Its low difficulty and low Reputation of 1300 makes it commonly a very casual Heroic Instance . Relative difficulty in Burning Crusade . Reputation requirements : Each key requires reputation with the respective faction . ( Lowered from in patch 2 . 3 . ) In , heroic mode dungeons have the following relative difficulty . Note that the heroic dungeons introduced in and don ' t require an attunement , but do require all characters in the group to be level - capped for the expansion ( 80 / 85 / etc . ) .
