Little help with Absorb Soul?

optimisi

well i started playing some days ago and i've been super happy with the class no problems at all but today, i found out that i can't learn Absorb Soul. and yes i have enough spirit.
but when i click on it to learn it, a small window appears saying 'prerequeisite skill level to low'. im trying to learn its first level, so yeah, i don't get it.
can somebody help me? tell me what i'm doing wrong or something? b:surrender

Erinea - Raging Tide

Check if you have the coin, spirit and the required culti for it.

Kagizyu - Heavens Tear

Maybe you dont have swirling mist yet. That would be prerequisite skill.

Or culti i dunno
