Somehow, the term Engineer has become synonymous with Turrets in video gaming, and in Guild Wars 2 it’s no different. There are a range of Turrets available to the Engineer, including close-range Flame turrets, longer-range Rifle Turrets, and friendly Healing Turrets. Turrets can be Overcharged to trigger a larger effect. Engineers also have Weapon Kits which replace the Engineer’s current weapon with something with a unique effect (such as a Flamethrower). Backpack Kits replace the Engineer’s set of skills centered around something specific, such as bombs.
Engineers can only equip Pistols in either hand, a Shield in the off-hand and a Rifle with both hands, but have plenty of other skills to make up for the lack of weapon choice.
Engineers also have a special set of 4 skills called "tool belt", triggered by keys F1-F4. Each slot skill you select (Keys 6-9) has a corresponding toolbelt skill. For example, if you select the Elixir H Healing skill, F1 will give you the option to Throw Elixir H, aiding your teammates. Also, if one of your slot skills is a turret, after placing your turret the corresponding tool belt skill will be replaced by a "detonate" button that causes the turret to explode, dealing damage. Tool belt skills have a separate cooldown from slot skills, which can be reduced by spending trait points in the "Tools" line, up to -30%. By combining the right slot skills with their toolbelt skills, Engineers can maximize their damage output or play a better role at supporting their allies by throwing potions, applying AoE buffs on allies and debuffs on enemies.
