Disclaimer: I wrote this as what I could understand, guided by Google Translate and its questionable translations.
Well, Gladiator, Bishop, Assassin and Enchanter first.
This is what I understood.
♤Assassin
Backstab (Reworked)
Damage +10%, Hit rate up by level.
Saddon Accelerator (?)-Passive
Based on that Assassins will have an skill that deals more damage when you use it from the front, do Backstab, and decreasing SD, and Sukia up by Agi.
Twilight Raid (?)-Active
And this other skill that its DPS is raised on poisoned enemies, drastically boosts Magic Eva giving a Buff, and synergies well with Phantom Step.
♡Bishop
Faith (Reworked)
When using attack skills, gives a buff called "Faith" which raises our Healing and Ailment Resist.
(It will work differently on Monk and Servant, I do not know how).
Bias Surge (?)-Active
This skill will consume the Faith buff, and do light magic area damage, while at the same time heals the party members.
Relinkish (?)-Passive
When Nemesis puts the enemies under an ailment, it adds a buff to the party called "God Punishment" which boost our party members damage.
The debuff from Resurrection is shortened each time the skill activates.
◇Gladiator
Berserk (Reworked)
Adds 10% of your Max HP to your base damage.
Melee and Magic R increases.
Scarface (?)-Passive
ATK Up when HP under 50%
Rampage (?)-Active
Increases Max HP, Damage, and Double Attack Rate.
Auto attack damage is boosted on enemies under ailments, boosts resistances (?)
♧Enchanter
Skill Weapon (IDK if its Draw or Enchant) (Reworked)
Autoskill rate +20%
Elementalize (?)-Passive
Gives a buff based on the last skill activated by Enchant Weapon, boosting its respective element magic and resistance.
Affected by Origin.
Attribute Length (?)-Active
Neutral Magic that ignores MDEF.
The element changes depending on the active Elementalize element.
*Apparently the calculations from Enchant Weapon autoskills will be changed.
