Guild Wars 2

I use a 10/10/10/20/20 aura and cantrip build

cantrips
10 fire grant 3 stacks of might
10 in water grant swiftness and regen

auras
10 air fury and swiftness
10 earth protection (armor of earth at 50% is also and option)

Other
10 water for faster cantrips faster, water spell cooldowns, or condition removal depending on the situation
20 in arcana for vigor on crits and buff based on attunments

With double daggers you have an aura in both water (water 4) and air (air 3) i put both of those as my auto attacks because I never sit in those attunments for long just swap in for some combos and out so the auras are always on CD.

you also have access to fire aura with us ring of fire (fire 4) and magentic grasp (earth 3) combos a fire aura on you.

also since you have 20 in arcana boons last longer

I run 2-3 cantrips depending on the the situation and what I need.

This will give you lots of boons and tons of mobility because with some crit you will have perma vigor. I also run with sigil that returns 50% of endurance on weapon swap if you jump attunments you can dodge SO much.

Lastly decide which boon is your favorite if it be protection, might, fury, or whatever and use a rune set that increases the duration of that boon if you really want to you can mix and match because many runes have the specific buff duration as the second set bonus

The key to this build keep moving and keep swapping attunments
