Introduction

The Ranger is one of the two specialized classes available to the Scout class once the player hits level 10. Rangers use bows and traps to take out the enemy while avoiding direct melee combat.

Although Rangers have training in daggers and swords, most Ranger builds will use the bow. Rangers are the best marksmen in the game, and their skillset reflects this, featuring primarily arrow-based skills.

Ability

Because Rangers work alone, these skills tend to reflect the need to silently kill an enemy and escape any situation with ease. For that reason, the Ranger has many arrow-based attacks that can poison an enemy for a slow and silent kill, or slow down an enemy so the Ranger can escape pursuit. They are also the only class able to see Assassins while they are in advanced hiding.

Rangers also understand that sometimes it is best to let your enemy come to you. For that reason, Rangers are trained in the art of trapping, allowing them to inflict hidden surprises on the enemy. Trap skills include the ability to blind, stun, hold, expose hidden enemies, and poison enemies. When the Ranger is working with allies, a well-placed trap can easily turn the tide of battle by disabling an opponent long enough for the group to rush him or her.

Solo Play

Much like the Assassin, the Ranger relies on a steady amount of offensive damage in order to defeat foes. However, most of this is done at long range with a bow before needing to get up close and personal. The various effects that can be placed with traps for use on opponents allows the Ranger to slow or damage enemies, keeping them at bay while unleashing a myriad of archery skills. Skilled soloists can even defeat most enemies with their sniping skills before ever having to switch to daggers or swords.

However, one must be vigilant, as Rangers are not helpless without a bow and can damage opponents easily with melee weapons. Evasion is the key to survival as a Ranger, as Leather Armor does not mitigate damage effectively.

Group Play

In group play, the Ranger has two roles to play. The major role is helping in dealing damage while a tank contains an opponent. This means he can stand back and let loose his variety of archery skills, while using its enmity-reducing skills to keep from pulling the enemy away from the tank.

The second role is to assist with controlling any extra enemies with skills that hold or sleep targets such as Sleep Arrow or Entangling Arrow. This allows a group to pull more than a single creature and still be able to focus on one before moving to the next. However, just as with other such skills, these tend to cause large amounts of enmity that will need to be negated with skills like Calming Whisper.
