Ranger

Ranger
Specialising in ranged attacks using a bow, they can root a target in place with their diverse skills, followed by powerful skills. However their HP an defense are both low being able to equip only leather armor.
They also have traps, activated once an enemy walks over it and can cause a number of status effects on the target.
Arrows and traps are depleted with every skill used so you always need to keep track of your inventory.

Unlike assassins, rangers are specialized in the use of bows. They are the only class that can use traps to stop the target and if situation calls, sneak behind an enemy and catch them unawares.

However they also need to purchase arrows and traps so they are more costly to maintain.

Much like assassins they have high dodge but due to the low attack speed of the bow once an enemy gets close they are at a disadvantage. Thus when fighting you must maintain distance. Thankfully they have a number of skills to prevent an enemy closing in and can equip daggers and long swords.

Soloing
Rangers are able to attack at a range and able to prevent or slow down the enemy's movement.

The most basic style is to damage the target with your ranged attack and keep your distance while slowly whittling away the target's HP or if the target somehow manages to close the distance, switch to your melee weapons.
However rangers lack the melee attack ability of assassins and don’t have many skills to aid when escaping so the use of traps is highly recommended.

Party play
In parties rangers take the role of a ranged damage dealer. They are also able to pull monsters.

However they have low defense and thus must be careful when managing aggro.

Generally speaking rangers have a lower dps than assassins or gladiators. However they also have a higher burst potential and can inflict a variety of status effects and can even replace sorcerers if the situation calls when disabling enemies.
