Guild Wars 2

What sigil should I use on my pistol?

At the moment, I am using full berserker gear with beryl orbs, and my sword has a Superior Sigil of Air.

I have a crit rate of about 53 and a crit damage of around 70 something. So really what I need is more power, more oomph.

Youve got a few choices. The top ones are probably:

Force – flat 5% damage
Accuracy – 5% crit rate
Rage – on crit you get quickness for a short while. Internal cooldown of 45 seconds

Those 3 will work in almost every situation.
You also have choices such as:

Bloodlust – 10 power per kill up to 250 power. lose all stacks on down.

It really depends on what you’re going for. If you’re looking to pvp, I suggest accuracy or force. Effects are constant, and always up, they also do not rely on you never being downed. If you’re doing general PvE then bloodlust is more than fine, as 25 stacks comes easy, and going downed is hard. And imo in dungeons rage works quite well, as 45 seconds is enough that it’s generally procced at the start of fights with trash mobs, letting you use your strongest moves early on without fear of interruption, and still have it cooled down by the next group.

If you need more power, I would go with a Sigil of Strength.

At that crit rate it will boost your might stacks immensly.
