Guild Wars 2

I don’t know which armor, trinkets and weapons shall I use for minion master.
Currently I’m using axe+dagger, 2nd weapons dagger+focus.
I just created exotic ruby ring and I have a feeling I wasted materials for nothing (Still didn’t equip it on me yet).
I have Jeweler 400 to create for myself some trinkets to start doing some serious damage. I’m aiming currently for PvE and I don’t want to sacrifice any of my minions on other skills. I use blood, bone, shadow fiends and flesh worm+golem.
I need an advice what stats shall I use for my new gear that soon I’m going to buy.
I want to do some serious damage.

As a pure minion master it doesn’t mater what stats you use, at least not for your minions. Their stats are fixed and do not scale with anything but level.
Hoever going for tanky items (knight, emerald) is generaly a good idea.

I’m using Carrion armor and emerald jewelery for a mix of vitality and toughness.
This way I can adapt my build towards power or conditions without switching gear.

Shall I go on coral or ruby?

Depends on your choice of weapons.
Read up on the basic game mechanics and make up your own mind.
Making your own decisions is always better then doing what people tell you without thinking.

This should provide most of the information you need.

Well, my choice is axe+dagger and dagger+focus.
What shall I focus on?

Here is what I have got >> focus on condition damage , power ( got it from 20 spite and little gears ) and toughness .
My build >> http://tinyurl.com/alxvkq7 >> check runes/sigils and traits.
My gear is carrion.

As our minions don’t benefit from our stats you should focus on condition damage as your main weapon should me Staff to heal them>
