This is a bug that has been confirmed to be working on World of Warcraft US servers, but doesn’t seem to be on EU. Basically if you kill Algalon really fast (under 6 secs) you will get Herald of the Titans title. The bug was confirmed in a 10 man group, all level 90 characters where everyone got the title and has been confirmed on US server many times since.
Algalon can be found in the hard mode-only encounter in Ulduar and you can find full instructions after the jump.
1. You have to form a group which has at least Damadgedealers, which deal 100k DPS or 200k Burst
2. You have to have at least 8 DDs in a group
3. Algalon has 8,3 M HP. You have to BURN him down as fast as you can (at least 1,3 – 1,6 M Raiddps)
4. You have exactly 6 seconds time to kill him before the system detects your gear. Therefore, it only counts if you have nuked him well before he runs behind his chest
5. When you done it right, you should have nuked him to 0 in 6 Seconds. When hes walking away to his chest, just wait and see if it pops up. It will pop up when Algalon despawnes and the chest stays available!
