How to obtain and use Attribute Infusions in Guild Wars 2

gamepur.com:

Infusions play a pretty significant role when you’re looking to complete end-game aspects of Guild Wars 2 with as little hassle as possible. Some of them are essential to progress in areas such as the Fractals of the Mists, and others are less vital and more pretty. Whatever your reasons, it can be somewhat confusing to figure out which Infusions are best for your character, particularly if they’re attached to a gold price.

Attribute Infusions, unlike Agony Resistance Infusions, provide the item that is used with a boost to the character’s base stats. You’ll need to equip it to an Ascended item in order to receive the boosts.

Infusions with the following names boost these stats:

Depending on the type of build you’re running on your character, you’ll want to select the relevant stats as needed. For instance, running a DPS thief will often mean you’ll want Mighty or Precise. On the other hand, if you’re running a supporting class, you’ll be looking for Mystical and Healing as the primary stats.

There are different levels of Attribute Infusions. Basic Attribute Infusions provide +4 to their allotted attribute, and you can purchase these from Laurel Merchants for 5 Laurels. The Standard Attribute Infusion gives +5 to their respective attribute and either a +5, +7 or +9 Agony Resistance.

These you can purchase from the INFUZ-5959 vendor in the Fractals of the Mists for three +5 Agony Infusions and 5 Integrated Fractal Matrices. Special Attribute Infusions are Infusions that you’ll obtain from completing various events or as low rate drops
