Staff Guard Sigil?
Well if you can stay alive bloodlust is nice.
However for greater burst air is fantastic when combined with fire.
I like putting Sigil of Stamina on (refills endurance on kill) and how well it works with Selfless Daring. Once the kills start rolling you can put out a bunch of healing while avoiding a bunch of damage, works even better with Renewed Justice adding blinds to the mix.
Fire sigil works well with staff so I’d always keep that on. Bloodlust can just as easily go on your second weapon set. You only need 5 kills for full stacks so you don’t really need it on your primary weapon. Make sure you put a Bloodlust sigil on your underwater weapon too so you don’t lose your stacks.
Outside of GvG’s where people don’t (shouldn’t) use stacking sigils, Bloodlust and Energy are the only way to go.
You need the added 250 power.
You need the extra dodge roll on disengage when you swap from hammer/greatsword to staff going into a restack.
