Builds do you all usually use for dungeons?
If you are casual player play anything you like and enjoy, it doesn’t matter.
For speedruns i would suggest you to use the current “meta” build. http://metabattle.com/wiki/Build:Dragonhunter_-_GS_Mace/Torch
I just use hammer and staff.
Hammer for bosses with 100% aoe protection uptime and staff for the mobs that ya don’t want to target one by one.
