Halflings gain a +7 armour bonus.
Most Suitable Roles
Halflings excel as Rangers, their small size making them nimble at dodging enemy attacks while being highly accurate with their bows, with their armour bonus augmenting the class' already heavy equipment.
Halfling Druids aren't as powerful with magic as their Elven counterparts, but with increased armour and dodge rate, along with a boost to the class' already impressive hit rate, they excel as front-line warriors, sometimes surpassing Fighters.
There is no particularly bad class for Halflings at all; they are pretty much good at everything they do.
