Shadow Dualist
This specialization is the evolution of the dodge tank. Their unique characteristic is manipulating the enemy's aggro and dodging their attacks to unleash fierce counter attacks.
Instead of using predict, they can attack and dodge with deft thrust.
There are many passives like Ray of Light and Lightweight which are useful for dodge tanking.
There's more freedom for different actions, since Phantom Swords provides dodging assistance, much more reliable than predict.
Other than dodge tanking, Lure and Revenge Thrust has explosive damage output, which both skills fufill their own little niches.


Ray of Light
Passive skill

Whenever the fencer is attacked, target rate and defense of all damage is increased.
For example, at level 5 if you dodge 5 attacks, then full defense will be increased by 30%.
Damage reduction resets when dodging fails.
This skill works well with other skills like Predict and Lightweight, where attacks that weren't dodged that would otherwise kill instantly are instead mittigated.
When shields are unequipped a message saying "usable skills have changed" will pop up. Ray of Light has no bearing on weather or not a shield is equiped, only accumilation of defense changes.


Counter boost
Passive

When Sylphid activates another attack will be added. Rate of counter and ammount of attacks are added when level of skill is increased.
Multiple hit attacks, and attaks from multiple enemies will activate Sylphid multiple times, there will be a counter attack for that amount of dodges.
If Sylphid and Counter boost are both at level 10, theoretically a maximum of 16 hits is possible.
At max level the ammount of counter attacks are dramatically increased, aswell as damage from counters. If damage from counter attacks is the main, then put this at max level.

Auto curtain
Not very reliable at max 25%, but doesn't spend TP.

Lure
Active skill
On the same turn, everytime an enemy attack is dodged allies on the same row as the fencer will attack with their equiped weapons
When multi hit attacks are dodged the number of countered attacks will activate after the attack is over, even if the fencer dies the attacks will still activate
If the targer dies during counter attacks, the remaining counters will be applied randomly to other enemies.
Dragoon's dragon roar works well with this skill in order to aggro attacks since the fencer can not aggro attacks by itself when using this skill.

Deft thrust.
Sword skill
Stab damage to one enemy. Increases aggro and dodge rate when this skill is used.
Has high speed modifier
Dodge and aggro rate is lower than predict, however the rates never go down, defense doesn't go down either making fencers with armor work well with this skill.
This skill works well together with Ray of Light.

Lightweight
Passive skill

The more empty equip slots, the higher dodge percentage.
May seem like a gimmick, but it is effective, Having 2-3 slots empty should suffice for good dodge rates.
Because you won't be able to use accessories for preventing ailments, you may want to use passive racial skills to prevent ailments.
It's better to remove all slots, than just half.

Revenge Thrust
Sword/Arm/Str based

Stab/Elec damage to one enemy. Inflicts more damage the more you dodge by the time the attack is cast. Even if a dodge fails, the counter will be preserved.
Basic damage stays the same when you level up the skill. Leveling the skill affects, charge number, and charge damage.
This skill can reach to ridiculous amounts of damage.
Everytime you dodge a charge counter increases.

Phantom Swords
Active skill/ Leg based

For three turns one enemy row will have lower aim rate. Turns increase through skill level.
Not as effective as blind, However blind resistance isn't a factor with this skill, meaning that this will keep the fencer safe.
Debuff with no damage, but cannot be used without a sword.
This skill is usefull when combined with shaman's Haste prayer.
This skill takes lots of TP so it must be used carefully.
