This is the WL skill tree. Basically the first three rows are higher level skills from the DM skill tree.
Here's a more detailed pic with most the skill's labeled.
Going by Jlvl rows:
Jlvl15 - Corruption, Stench of Faility, Mind Crisis
Jlvl20 - Mana Burn, Strength of Darkness, Petrified Stench, Shield of Nightmare, Wide Windy Shackles
Jlvl25 - Magic Skin, Corpse Explosion, Neutralize Magic
Jlvl30 - Fear Trap, Steadfast ShadowFlame(Hold Trap)
Jlvl35 - Explosion Trap, Stench of Armistice, Lightning Trap(Stun Trap)
Jlvl40 - Shadow Antrophia, Deep Evasion, Fog of Horror
In difference to the Nuker-CM class, Warlocks instead have traps, corpse skills, and alot more debuffs at higher levels than CM's. Funny though how we’re the only mage class who has lower buffs than our counter 2nd class.
