Titan - Defender

The Defender is the second subclass of Titans which is unlocked once the player reaches LV15. As the name implies, Defenders focus on further strengthening the Titan's already impressive defensive capabilities to the benefit of the user and his allies.

Grenades

Each class have the ability to use three different grenades but only one can be carried at a time. Grenades have a cooldown of 55 seconds. The stat attribute Discipline reduces the cooldown timer of grenades, allowing you to use this ability more often.

Magnetic	A grenade that attaches itself to enemies before exploding twice.
Spike Grenade	This sticky grenade will attach to any surface before damaging surrounding enemies using a Void Light explosion
Suppressor Grenade	This grenade temporarily prevents enemies from using special abilities.

Movement

Each class have their own movement ability. This allows them to cover more distances, reach higher ground, or just simply become more mobile. The Titans' movement ability is Lift. There are three modifiers which can only be activated one at a time.

Increased Height	Allows Titans to reach higher elevation using Lift.
Increased Control	Players will have better control mid-air during lift
Catapult	Enables Lift to have a burst of momentum.

Super Ability

Defenders can use Ward of Dawn where they deploy an impressive defensive barrier around them. The attribute Intellect also improves the cooldown of super abilities. Like the grenades and movement skills, there are three bonus modifiers that can improve the Ward of Dawn's effects but only one can be activated at a time.

Armor of Light	The Defender and his allies will have significant damage resistance while inside the Ward of Dawn.
Blessing of Light	Passing through the Ward of Dawn will bless players with a temporary shield.
Weapons of Light	Passing through the Ward of Dawn will bless players with a temporary increase in weapon damage

Melee

Defenders can use the melee skill Disintegrate. Killing an enemy with this powerful melee strike will deploy a Force Barrier that will soak up damage for 15 seconds or until the bonus shield is depleted.

War Machine	While Force Barrier is active, you'll be able to reload and switch weapons very fast.
Unbreakable	The Force Barrier will recharge continuously.
Gift of Light	When Force Barrier is active, all melee kills will generate Orbs of Light. (Collecting these will reduce the cooldown of your Super)
