I found out about a slightly easier way of completing the "intense cold" achievement: Intense Cold
Defeat Keristrasza in The Nexus on Heroic Difficulty without allowing Intense Cold to reach more than two stacks.
Some basic facts regarding to this achievement: First of all, you can have 1 or 2 stacks of the debuff, but if u ever get 3 you are out. The normal way of doing it would be to have a priest/paladin in your party, ask him to dispel you as soon as you get frozen. (A macro "/cast [target=YOURNAMEHERE] cleanse/dispel" works great)
But often you can't get a dedicated dispeller, there's an easier way: DIE DURING THE ENCOUNTER: if you have never gotten more than 2 stacks and died, when your party killed the boss, you will get the achievement. It might be common sense but i didn't know that until I got my achievement that way.
Similarly, "Snakes, why'd it have to be snakes" can be done the same way. Snakes. Why'd It Have To Be Snakes? : Defeat Slad'ran in Gundrak on Heroic Difficulty without getting snake wrapped. If you die before ever getting wrapped, you'll get the achievements when your party kills the boss.
If you are a warrior/DK/druid/hunter you can taunt the boss off of tank and hopefully get one shotted; any other class you can always stand in front of the boss and hope you get cleaved or something.
Hope this helps![]()
