So, on Friday night, I was invited to go to a Ulduar hardmode/achievement run dealio. Now, I've done the Kologarn hard mode previously (one of our warlocks wasn't paying attention and blasted the wrong arm for the whole fight).
Anyways, I haven't really done much of Ulduar (well, ok, now I've done 12/14) so it was great to see the encounters- especially on hard mode.
For Flame Leviathan, with all four towers activated, that field which is normally so plain, and boring, and easy- well- its a mess. A very glorious mess. There are fires, frost beams, lightning storms, plants, vehicles running everywhere... I loved wiping on that fight for a while. We then decided that four were too many and just did three- but it was still fun.
We moved onto Razorscale, which just takes a lot of time and focus on
not killing the adds, and then bringing them down to the appropriate health. We reset it at one point (I'm not sure why, I think it was to avoid the enrage timer) and on our next attempt we brought her down twice and the second time we got our achieve so we knocked her dead and got
another achievement.
For Ignis, you tank him in the water so he doesn't have to get moved around- as long as you kill him within the achievement parameters, the extra 20% damage per add shouldn't be an issue for your tank. Its a simple enough fight.
For XT-002 Deconstructor, taking out his heart is easy. Now, while it says its only a 15% increase in damage, his tantrum damage is easily 100% more. Other than that and some void zones (from gravity bombs) and little adds (from light bombs) its a tank and spank.
We ended the night on Kologarn, but there was some timing error and one of his arms died too quickly, so we didn't get the achievement.
