DREAMBREATH

The eight dungeons, compared

Which dungeon hits hardest, how long each one runs, and how many pulls you have to learn by name.

Log-verifiedn=2672 runs · +10 to +14
Murder Row has the hardest five seconds for the whole party at 11,913,990. Leave the tank out and Den of Nalorakk is worse for everyone else, at 8,265,879.
Two different questions. The party figure counts all five players, and the tank takes most of it. The other leaves the tank out, which is the damage you have to answer.

Melee is not your problem. Of the damage that lands on anyone except the tank, melee is under 3% in 7 of the 8 dungeons. Altar of Fangs is the exception at 9%.
Autoattacks land on whoever is holding the pack. Melee is a large share of what the party takes, between 26% and 37% depending on the dungeon, and almost none of it reaches anyone else. Plan around abilities.

Sorted by the worst five seconds on everyone except the tank. Duplicate reports of the same key and runs whose event stream was cut short are left out, which is why these counts are lower than the raw log count.

Season 2 dungeons compared by length, pull count, worst five seconds on everyone except the tank and on all five players, and how much of the non-tank damage is melee.
