The Zealot class is one of the specialization classes of the Tumerok Melee tree. (The other is the Feral Intendant.) You can choose a character class when your Tumerok character reaches level 15. By choosing the Zealot, you gain access to a set of specialized skills that require the use of 2 Handblade weapons.
"As if taking their cue from the creatures of the wild, Tumerok Zealots channel their energies into powerful offensive and defensive skills. Expressed in combat, Zealot skills soften their opponents' defenses before overwhelming them with bloodletting attacks."
"Zealot skills include:
Bone Crusher, Spine Ripper, Back Breaker: Powerful bloodletting attacks.
Ride the Anger: Increases the user's attack speed.
Serpentine Evasion: Increases the user's melee defense.
Screen: Gives the user a chance to resist incoming negative effects."

Quick Guide to the Zealot
If you want to risk your life on a daily basis, choose the Zealot. This class is the Tumerok melee damage-dealer (DD) class, the Tonk answer to the Berserker, and the king of single-target damage. Unlike the Berserker, you have no Area-of-Effect (AOE) attacks unless you take Hurricane from the base Melee tree. Do not despair about lack of AOE, and prepare to get your name written in blood on the corpses of big quest bosses. Due to powerful percentage bloodletting attacks, the Zealot in the group is almost always guaranteed to do the most damage on a high-health boss. (If you're a truly vain Zealot, though, you'll steer clear of the Juggernauts, who can do something similar.) In short, you are born to kill Big Stuff.
By wielding two handblades, you do not give up your base melee skills, but you get access to excellent and often life-saving Zealot-specific skills and buffs.

Bonus Damage Pool
This is the default passive given to all classes who don't get Health Increase or Vigor Increase. Tanks and Healers do NOT get this passive. For each point, the Bonus Damage Pool increases by 1. The total Damage Pool has a percentage chance to be added to an attack. Different attacks have a different percentage chance to apply the Damage Pool, but they generally follow this system:
Auto-attacks: 10% chance to add the Damage Pool to their damage.
Weak attacks (which do 75 damage at level 50): 40% chance to add the Damage Pool to their damage.
Medium attacks (which do 200 damage at level 50): 60% chance to add the Damage Pool to their damage.
Strong attacks (which do 260 damage at level 50): 80% chance to add the Damage Pool to their damage.
Hero attacks (which do 340 damage at level 50): 90% chance to add the Damage Pool to their damage.
Other skills which fall in between these numbers have appropriate percentage. For instance, a skill which does 100 damage at level 50 has a 45% chance to add the Damage Pool to its damage.
Note that the Damage Pool only gets added once per attack. So a multi-hit attack will only add the Damage Pool to at most one of the hits. However, if the first hit in a multi-hit attack doesn't add the Damage Pool, each subsequent hit has a chance to add the Damage Pool, until one of the hits succeeds in adding the Damage Pool.
