Mr Blue letter #3 for kTERA's T4 update reveals new skills and mounts

Fresh news while your having your cup of coffee or tea. Mr Blue has just revealed another set of screenshots for the upcoming T4 update in Korea. This time it features new skills and the new mounts which you might have seen previously. As usual, my fantranslations so nothing is set in stone.


New Lancer Skill - Harpoon Chain (작살 사슬)



Having a hard time dealing with numerous monsters at the same time or defending your healer? Chain nearby located enemies together while your party members can clean up the mess around you.

New Sorcerer Skill - Petrifying Armor (암석화)



Due to the light armor Sorcerers are fragile, for this reason they can now shield themselves with a rock solid armor that raises their defense and prevents them to get hit by physical and magical skills. While in petrified state the Sorcerer won't be able to attack.


New mounts


Ancient War Horse


Undead Horse


Zebra


Black Panther

SOOO SEXY!!!! *o*

You are making it very difficult for me to wait for this game!! >.<

The zebra is very MEHHH the rest is awesome:D

panther just looks like a regular panther...nothing notable at all....

as for the wizard skill, best rooting defense skill effect. it actually does what it says.

OMG Panther... me wants ^.^

Gotta have 'em ALL!! Especially the Undead Horse and the Panther!

I swear, all my money is going to go into buying mounts in this damn game.

<span style="color: #66CCAD;"> Can't have a fantasy game without battle cats! The Roman style ancient war horse is regal. Classy how the rider of the Undead horse is riding side saddle. </span>
