The Druid class is a new class with the STR/INT attribute. This makes them start at the same location as the Templar class, with proximity towards the Strength and Intelligence portions of the passive skill tree.
As the class name suggests, Druids will specialize in Shapeshifting Spells/Skills.
This style of gameplay is new for Path of Exile, and many players are looking forward to trying out the new class.
While the Bear form of Druid has been teased, the Druid isn’t necessarily built for being tanky. From gameplay we’ve seen so far, the Druid is a mixture of melee and spellcasting, which matches the STR/INT attributes well.
With the starting location, we can assume that Druids will lean toward things like Armour/Life/Energy Shield for defense. For offense, the Druid will likely focus on a mixture of physical, fire, and/or lightning damage.
Shapeshifting

In the gameplay we see, the Druid character uses a mixture of spells and Shapeshift spells. Because of this, your character will often switch between human and animal form.
When you use a skill, you will automatically transform between the correct form. However, there is a slight delay to transform, so you’ll want to be cognizant of your skill order. Use your regular spells while human and transform into a Bear to start slamming the ground.
This style of gameplay is further augmented by the Dual Specialization system. You can set one weapon loadout for your regular spells, and the other for when you’re transformed. This way, you can build a strong weapon for spells, and another for your Bear slams.
Easter Egg: When dodge rolling, you will automatically swap back to human form in combat. However, if you’re in town, you can roll around in bear form.
