Power/Armor/Vit Armor Insignias are uncraftable
The armour you can buy from joining the Vigil has Power, Toughness & Vitality.
There are actually a lot of combinations that are not available through crafting, not just this one. I’m sure it is intentional to add variety to the game that you might have to use different sources to get different combinations of stats. I consider the current crafting options to be sufficient for the majority of players and you can use other sources for the remaining combinations.
There are others that cant be crafted. 3 of them i beleave.
As near as I can tell these are the available stat combinations.
Craftable stats:
Power/Critical Damage/Precision
Magic Find/Power/Precision
Toughness/Power/Precision
Condition Damage/Power/Vitality
Condition Damage/Power/Precision
Critical Damage/Power/Vitality
Healing Power/Power/Toughness
Other stat combinations that are available in the game:
Condition Damage/Precision/Toughness
Healing Power/Precision/Vitality
Precision/Power/Condition Damage
Vitality/Healing Power/Condition Damage
Power/Toughness/Vitality
Magic Find/Power/Condition Damage
When first we practice to deceive.
You can also get power/toughness/vit exotics by cashing in tokens from WvW, Sorrows Embrace explorable and something else explorable
