Twin Saga Hunter

Ultimate skills cost 1000 SP to use. All cooldowns are 30.0 seconds. Unlocked by using a Hunter. Braids for men.

Title says it all.I've leved a few classes to 20, Hunter is the one I'm planning to keep. Currently level 28 with Hunter class at 25.I feel like I'm obviously missing something very basic since I started playing yesterday. Anyway, I keep using my ultimate skill and it always uses the same one I used as Monk (which was my starter class). Tried Mage, Cleric, Hunter, all I see is the same blue projectiles thingy or the melee combo where it finishes by stepping on my target's head. Faceless dolls dominican republic meaning.

I set a different ultimate skill pressing K with different classes and tried every single one of them but nothing changes.Am I missing something here?
