This build has been designed for optimised 4-person dungeon content more specifically for veteran and hardmode dungeons. If you are looking for a more beginner friendly dungeon build, then check out the Beginner Tank Builds page and our YouTube channel.
When it comes to an optimised build for 4-person content there are a few different options to consider depending on your group such as what classes the other people are and if you are with 3 Damage Dealers or 2 Damage Dealers and 1 Healer.
When it comes to dungeons content there are a lot more good options for Tank setup compared to trials. The most important thing for 4-person content is individual performance, and your gear choices will only be affecting 2-3 damage dealers, so the way gear sets work and perform are very different compared to a 12-person trial with 8 damage dealers.
