What it does: It stacks auras on 5 of your party members who are close to you. Each time you apply an aura they get protection, swiftness and fury. Each one of your signets will pop an aura. This helps the rest of the team including you take less damage, deal more damage and can kite better. The range is rather small for who gets the aura, so it is more melee friendly.
What weapons you use: You can use a different weapon for each situational encounter. I usually stay in scepter/focus for more survivability and swap to staff when I need heavy AoE or to destroy objects like burrows in AC exporables. D/D will give you the most auras (2) but it is also the hardest to use if you have trouble staying alive. Focus has a fire aura and staff has an earth aura. Scepters don't have any aura.
What equipment you need: It depends on what you want to gear for. If you're absolutely great at dodging use berserker's(pow/pre/critdmg) all you want for more damage. If you want to live use soldier's(pow/vit/tgh). I've been using a mixed set with relatively balanced stats so that I can live longer and deal damage. I've tried condition damage equipment for it but you need to stack condition damage at the cost of your power and you'll be forced to stay in earth attunement for the majority of the time just to stack bleeds, which can stack up to 11-13. If you're willing to stay in earth, than spec that if you want.
What runes and sigils are good: I think one of the best sigils for dungeon runs is the chill on swap. Since attunement swapping counts as weapon swapping, you can basically cast it all the time. You're getting another chill to on top of signet of water and water focus 4 skill. The same goes for 3 might on swap and +50% endurance on swap. For runes I would try to find +boon duration or +prot duration and stack those. This will let the aura's buffs last much longer.
This point of this build isn't to do the most damage or tank, it's to help everyone do more damage while keeping them alive, but you're no good at that if you don't stack vit/tough because you will die.
If you have any more questions or see something I've missed please point it out. If you want a leveling build of this just swap your traits in the water line into the earth line and the attune line. 30 earth/10 attune for retained signet passives and boons on attunement swap.
Hope this helps! <3
