As with the Halls of Stone achievement this is the standard achievement for defeating each instance on heroic mode. Simply make your way through the instance (while on heroic mode) and kill all four bosses. The bosses in Halls of Lightning are a little more difficult than Halls of Stone, but with just a little bit of strategy you will be ready to waltz your way through the instance and earn this achievement. Along the way look at the individual boss achievements as well, done correctly you can finish the instance with four achievements completed.
General Bjarngrim – The general is the first boss in the instance and patrols around the first walkway that you come to. To fight him you first need to clear the guards around the section of walkway where you want to fight him. This is usually the right hand lower side, but can be either side. Once the area is clear, wait for him to patrol near and have the tank engage.
Once the tank is engaged you simply need to have him faced way from the group, since he has a frontal cleave attack. He will have two adds with him that need to be killed first, as they heal him. Once they are down DPS should switch to him. Every once in a while he will whirlwind attack hitting everyone around him, so melee DPS needs to watch for this and back away. Also, when he cleaves he applies a mortal strike debuff to the tank, so healers need to watch for it and heal through it.
This is only slight variation from the normal fight, and one that many players complete by accident. It is also a great achievement since it probably is paying homage to the AC/DC classic Thunderstruck. Before General Bjarngrim patrols to the outer platforms he stops at the inner ones and becomes buffed with an electrical charge. This charge allows him to do more damage which makes the fight more healer intensive. It really isn’t that hard though, so go for it the first time through.
Volkhan – This is another simple fight. Every once in a while Volkhan summons two Golems who have their own aggro table. When they reach 1% they become brittle and will freeze in place. When Volkhan stomps it will cause any brittle golems to shatter and explode. This explosion causes a lot of damage to anyone near the golems, so when you see shatter being cast, everyone should run away.
This is another relatively easy achievement that you have two choices on how to achieve it. The first is to simply burn Volkhan down faster than he can summon out and detonate two groups of Golems. This is pretty easy to do with any raid geared group. The second option is to have a player grab aggro on the golems and run them away from Volkhan. As they take damage they slow down, so drop them to 50% or below and anyone can kite them easily.
Ionar – Ionar is a lightning elemental that often breaks into balls of lightning that chase players down before he reforms. This is an annoying fight for many groups. Not because it is difficult, but because it can take a significant amount of time. There are two methods to defeat him. Both involve avoiding him when he becomes the balls of lightning, which can not be harmed. Some groups spread out on his platform and just dance around the lightning which randomly chases players. Other groups choose to run back down the hall in the direction that they came from and wait until he reforms. Both methods work, the first is faster, assuming players can react quickly and stay spread out.
Loken – The only difficult part of this fight is deciding if your group can out heal the Lightning Nova or if you need to clear away from him. If everyone in the group has over 16,000 health it is strongly suggested that everyone just stay in melee range of Loken the whole fight and eat the lightning nova. If not everyone in the group does, then players with less than 16,000 must run away from Loken when he starts casting Lightning Nova and then run back into melee range as soon as he has finished. Either way as soon as Lightning Nova damages everyone, the healer gets all players health back to maximum in preparation for the next nova. Other than that it is a DPS race.
This achievement needs everyone to be in raid level gear and to just burst DPS Lokin down. You can finish him off very easily with only mediocre DPS of 2,500 DPS per DPS player. If you have a hunter for a nature resistance aura, and an AOE healer it helps a lot.
