***Attention***
This information is copied directly from Wowhead: Makes web browsers happy!. However I though I would post it here cause some folks still have trouble with multiple tabs in Firefox. I would also like to add that with the information I gathered from here, I was able to solo this with a Discipline priest. I will add an update asap.
Op - Lord Ahune - NPC - World of Warcraft
TRY THIS SOLO AT YOUR OWN RISK!
Only a few people I've talked to succeeded at soloing this and you'll waste your summon if you fail.
The boss is level 73, yes, the BOSS ITSELF IS IN FACT VERY EASY, he doesn't do ANYTHING for phase 1.
Phase 1:
The boss does nothing at all, and yet this is where everyone dies! The problem is that the boss spawns about 3 new adds every 5 seconds (all level 70). The adds are ALSO EASY, they have 1750 hp and go down in 1-2 hits, but the problem is that you are CONSTANTLY OUTNUMBERED due to their fast spawn rate. Note also that the boss and adds are Frost resistant.
The adds use ranged shots for ~300-500 damage, and you will soon be getting hit by loads of them. There's also a BIG add with ~80k hp.
Spikes also appear on the ground; walk away when you see them or you will get thrown into the air! You will be unable to use bandages since the spikes form rapidly and you won't have time to bandage for more than 1-5 seconds.
Most people don't get to see phase 2.
Phase 2:
If you survive the assault, the Ice Giant retreats into the ground and a crystal appears; shoot it as fast and as much as you can. It goes back to Phase 1 when he re-appears.
Some people (like me, BM hunter using PvM tankpet and tankspec for grinding) made it through 1 phase before they had to admit defeat due to lack of healing.
Here's the problem when soloing:
DPS: Good against the boss and at killing the adds quickly, but due to there being no healing, your health will just keep getting lower and lower and lower, and eventually you will be defeated even if you do manage to live through Phase 1. Remember that Bandages are useless due to the spikes, and you can only use a potion once.
Healing: Forget it. Every priest I've talked to has failed badly. Sure you can heal yourselves massively. So what? You will be getting hit by 20 adds that constantly push back your spells, and forget having time to cast any damaging spells apart from DoTs. Game over for these classes.
No longer the case.. as Discipline I Spent my time Holy Nova'ing for the little adds, 2 pops a piece. and kept both my DP, and SW:P on the big rock adds. Also Keeping a Renew, Shield, and PoM up helped tons. Save your Pain Suppression for if you get in a Jackpot. I also was Flasked with "Frost Wyrm" and Stamina foord. as well as I wore half of my PvP set, and my Frost resist belt.. Potion of Speed helps out alot during the Frozen core phase. GL :P
Tank: Forget it. Sure you can absorb the assault of mobs but your DPS will be too low to burn through the boss and adds fast enough.
I know 2xWarriors that have done this already this year, one is prot, and the other is Fury. The adds don't hit all that hard anymore... Just make sure like I stated in the priest section that you are prepared, Flask, Frost res, Stamina gear.
As far as I can tell the only difference in the two warriors, was that the Prot warrior needed "3" Core phases. And was swapping weapons during said phase. He also used Bandages and pots, and had a Fort/Kings buff. But that is all.
And here's where hybrids actually have a chance:
Druids: Tank, DPS and Healer in one, you should have an easier job than other classes.
Blood Death Knights: Come on, massive damage, plate and self-healing based on outgoing damage? Should work with this class.
Paladins: Enough said... Edit: Oh, magically my post was given one downvote at the same time as the below Paladin Elnarr posted that he had soloed it. I guess the truth hurts. ;-) Having pointed that out, I am sure more paladins will vote me down... :-(* Haha. Edit2: And now he's heading down a slippery slope at -13... funny how things can backfire. :-)
Update: Funny how accurate the above statement turned out to be:
Here's the current count of people who have replied "I soleed it lolz so eazy! [insert generic button presses here that anyone could do if their class had been as powerful as paladins]":
Paladins: 9 (6 Retribution, 3 Prot.)
Druids: 2 (2 Feral)
Death Knights: 2 (1 Blood, 1 Unholy)
Warriors: 1 (1 Protection who is REALLY well geared! For your next trick, repeat it in blues like paladins ;-)).
This pattern reinforces my observations that it's only really safely soloable (or doable at all) with hybrid classes. For other classes, the outcome is heavily stacked against you and will be very gear dependent.
Update: Rubyloc wins the "think-before-you-type comment of the week" award for this one:
"Killed both normal and heroic versions today. Really easily soloed as retribution paladin, a shame really - they should've upped the level to 80." -- because everything revolves around the most overpowered class in the game (along with DKs)? I just had to quote this in case his post gets purged, it made me laugh. ;-)
Now the difference between Heroic and Normal:
A couple of things change on Heroic; of course the adds and boss have more HP and hit harder, but you also get... *drumroll* a BC badge and FOUR EXTRA CRAPPY ITEMS! Yes, for putting yourselves through Heroic mode, you'll win some Level 70 necklaces, congratulations! They are useless.
BUT there IS a bonus to Heroic: First off, if you wipe on heroic you don't lose your summon (you do on normal). Why not? Because there is no quest on heroic! You just click the frost stone**! (On normal you get a quest at the entrance and lose it when you start the summon). This also means that you can do the quest on normal AND the heroic non-quest summon all in one day! For a group of 5 people that's 6 summons (the heroic version is treated like a regular boss and only reappears when the instance resets).
** Don't lick it, you'll get stuck. I know it's tempting, it looks like a big ice cube... Mmm... ~~ ice cubes ~~~~ *drool* ... what do you mean I'm the only one with an ice-cube fetish? Stop looking at me like that!
Hint: If you want to do an unneccessary pre-quest, then start here instead. You might as well do it since I am pretty sure it will count towards your loremaster achievement.
Things that drop on both Normal and Heroic:
When he dies, he drops an enchanting recipe, a scythe, a massively cool pet, some beer, HIS FRICKING TESTICLES (he always drops a pair), four extremely crappy cloaks, and a quest item (always drops but you can only get it once) which rewards one of two possible tabards (summer flames or summer skies, both sounding like porn star names).
So remember, bring some friends and enjoy, then get the hell out of there when you get what you wanted! Ie: THIS...
Also note that none of the items can be disenchanted. Remember this was posted as a learning tool, A way to go into said encounter with some knowledge and understanding. NOT a 100% I win guide. I know plenty of folks that have neither the skill nor the patience to pull this off. Gl :P
